The probability of getting tails on a coin flip is 1/2 or 0.5.
The probability of getting tails on two consecutive coin flips is (1/2) * (1/2) = 1/4 or 0.25.
Therefore, the probability of getting tails and then getting tails is 1/4 or 0.25.

What is the probability of picking an odd number and then picking an even number? Write your answer as a fraction or whole number
There are a total of 4 numbers: 3, 4, 5, and 6.
The probability of picking an odd number on the first card is 2/4 or 1/2 (since there are 2 odd numbers out of 4 total numbers).
After picking an odd number, there are 3 numbers left in the deck, of which 2 are even. Therefore, the probability of picking an even number on the second card given that the first card was odd is 2/3.
The probability of picking an odd number and then picking an even number is the product of the two probabilities: (1/2) * (2/3) = 2/6.
Simplifying the fraction, the probability is 1/3.
Therefore, the probability of picking an odd number and then picking an even number is 1/3.

What is the probability of landing on a 4 and then landing on an even number? Write your answer as a fraction or whole number.
There are a total of 3 numbers on the spinner: 3, 4, and 5.
The probability of landing on a 4 on the first spin is 1/3.
After landing on a 4, there are still 3 numbers on the spinner, but only one of them is even: the number 4.
Therefore, the probability of landing on an even number on the second spin given that the first spin landed on a 4 is 1/3.
The probability of landing on a 4 and then landing on an even number is the product of the two probabilities: (1/3) * (1/3) = 1/9.
Therefore, the probability of landing on a 4 and then landing on an even number is 1/9.
The probability of landing on a 4 on the first spin is 1/3.
After landing on a 4, there are still 3 numbers on the spinner, but only one of them is even: the number 4.
Therefore, the probability of landing on an even number on the second spin given that the first spin landed on a 4 is 1/3.
The probability of landing on a 4 and then landing on an even number is the product of the two probabilities: (1/3) * (1/3) = 1/9.
Therefore, the probability of landing on a 4 and then landing on an even number is 1/9.
You pick a card at random. Without putting the first card back, you pick a second card at random.
Numbers on cards: 1-8
What is the probability of picking a 7 and then picking an even number? Write your answer as a fraction or whole number.
Numbers on cards: 1-8
What is the probability of picking a 7 and then picking an even number? Write your answer as a fraction or whole number.
There are a total of 8 numbers: 1, 2, 3, 4, 5, 6, 7, and 8.
The probability of picking a 7 on the first card is 1/8.
After picking a 7, there are 7 numbers left in the deck. There are 4 even numbers among the remaining 7: 2, 4, 6, and 8.
Therefore, the probability of picking an even number on the second card given that the first card was a 7 is 4/7.
The probability of picking a 7 and then picking an even number is the product of the two probabilities: (1/8) * (4/7) = 4/56 = 1/14.
Therefore, the probability of picking a 7 and then picking an even number is 1/14.
The probability of picking a 7 on the first card is 1/8.
After picking a 7, there are 7 numbers left in the deck. There are 4 even numbers among the remaining 7: 2, 4, 6, and 8.
Therefore, the probability of picking an even number on the second card given that the first card was a 7 is 4/7.
The probability of picking a 7 and then picking an even number is the product of the two probabilities: (1/8) * (4/7) = 4/56 = 1/14.
Therefore, the probability of picking a 7 and then picking an even number is 1/14.
You pick a card at random, put it back, and then pick another card at random.
Number on cards: 1-5
What is the probability of picking a number greater than 4 and then picking a number less than 2? Write your answer as a percentage.
Number on cards: 1-5
What is the probability of picking a number greater than 4 and then picking a number less than 2? Write your answer as a percentage.
There are a total of 5 numbers: 1, 2, 3, 4, and 5.
The probability of picking a number greater than 4 on the first card is 1/5, because there is only one number greater than 4 in the set (which is 5).
The probability of picking a number less than 2 on the second card is also 1/5, because there is only one number less than 2 in the set (which is 1).
The probability of picking a number greater than 4 and then picking a number less than 2 is the product of the two probabilities: (1/5) * (1/5) = 1/25.
Converting 1/25 to a percentage:
1/25 = 0.04, which is equivalent to 4%.
Therefore, the probability of picking a number greater than 4 and then picking a number less than 2 is 4%.
The probability of picking a number greater than 4 on the first card is 1/5, because there is only one number greater than 4 in the set (which is 5).
The probability of picking a number less than 2 on the second card is also 1/5, because there is only one number less than 2 in the set (which is 1).
The probability of picking a number greater than 4 and then picking a number less than 2 is the product of the two probabilities: (1/5) * (1/5) = 1/25.
Converting 1/25 to a percentage:
1/25 = 0.04, which is equivalent to 4%.
Therefore, the probability of picking a number greater than 4 and then picking a number less than 2 is 4%.
