Marissa is researching information about martial arts students. She found that 7 out of 12 martial artists practice every day. There are 144 martial arts students at a school.
A. Predict how many students practice every day.
B. What is the sample size?
A. Predict how many students practice every day.
B. What is the sample size?
A. To predict how many students practice every day, we can set up a proportion:
7/12 = x/144
Solving for x, we get:
x = (7/12) * 144
x = 84
Therefore, we can predict that 84 martial arts students practice every day.
B. The sample size is the number of martial arts students that Marissa researched, which is 12.
7/12 = x/144
Solving for x, we get:
x = (7/12) * 144
x = 84
Therefore, we can predict that 84 martial arts students practice every day.
B. The sample size is the number of martial arts students that Marissa researched, which is 12.
You roll a number cube twice. Find P (even, then not 2). Write the probability as a fraction in simplest form.
The number cube has six equally likely outcomes: 1, 2, 3, 4, 5, or 6.
To find P(even, then not 2), we need to find the probability of rolling an even number on the first roll and a number that is not 2 on the second roll.
The even numbers on the number cube are 2, 4, and 6. So the probability of rolling an even number on the first roll is 3/6 or 1/2.
After rolling an even number on the first roll, there are five equally likely outcomes remaining: 1, 3, 4, 5, and 6. Only one of these outcomes is a 2, so the probability of not rolling a 2 on the second roll is 4/5.
To find the probability of both events happening, we multiply the probabilities:
P(even, then not 2) = (1/2) * (4/5)
P(even, then not 2) = 2/5
Therefore, the probability of rolling an even number on the first roll and a number that is not 2 on the second roll is 2/5.

Therefore, the probability of rolling an even number on the first roll and a number that is not 2 on the second roll is 2/5.
A number cube is rolled 450 times. The number 3 comes up 67 times.
A. What is the theoretical probability of rolling a 3? Write your answer as a fraction in simplest form.
B. What is the experimental probability of rolling a 3? Write your answer as a fraction in simplest form.
A. What is the theoretical probability of rolling a 3? Write your answer as a fraction in simplest form.
B. What is the experimental probability of rolling a 3? Write your answer as a fraction in simplest form.
A. The theoretical probability of rolling a 3 on a number cube is 1/6. This is because there are 6 equally likely outcomes (numbers 1 through 6) and only one of them is a 3.
Therefore, the theoretical probability of rolling a 3 is 1/6.
B. The experimental probability of rolling a 3 is found by dividing the number of times a 3 was rolled by the total number of rolls:
Experimental probability of rolling a 3 = number of times 3 was rolled / total number of rolls
Experimental probability of rolling a 3 = 67 / 450
Simplifying the fraction by dividing the numerator and denominator by 5, we get:
Experimental probability of rolling a 3 = 13/90
Therefore, the experimental probability of rolling a 3 is 13/90.
Therefore, the theoretical probability of rolling a 3 is 1/6.
B. The experimental probability of rolling a 3 is found by dividing the number of times a 3 was rolled by the total number of rolls:
Experimental probability of rolling a 3 = number of times 3 was rolled / total number of rolls
Experimental probability of rolling a 3 = 67 / 450
Simplifying the fraction by dividing the numerator and denominator by 5, we get:
Experimental probability of rolling a 3 = 13/90
Therefore, the experimental probability of rolling a 3 is 13/90.
You mix the letters M, A, T, H, E, M, A, T, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability P (A). Write the probability as:
A. A fraction in simplest form
B. A decimal
C. A percent
A. A fraction in simplest form
B. A decimal
C. A percent
There are 12 letters in total, including 2 'A's. Therefore:
A. The probability of drawing an 'A' is 2/12, which simplifies to 1/6.
B. The decimal of the probability is 0.166666...
C. Converting the decimal to a percent, we get that the probability of drawing an 'A' is approximately 16.67%.
