Calculate the theoretical probability of rolling a total of 7 or 11 on a pair of number cubes from a single toss.
P ( 7 or 11 )= ____
P ( 7 or 11 )= ____
To calculate the theoretical probability of rolling a total of 7 or 11 on a pair of number cubes from a single toss, we first need to find all the possible outcomes.
When rolling two dice, the total outcomes are 6 * 6 = 36.
The combinations of possible outcomes that result in 7 are (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). So, there are 6 ways to get a total of 7.
The combinations of possible outcomes that result in 11 are (5, 6) and (6, 5). So, there are 2 ways to get a total of 11.
Therefore, the total number of successful outcomes is 6 (for 7) + 2 (for 11) = 8.
The probability of rolling a total of 7 or 11 on a pair of number cubes from a single toss is:
P(7 or 11) = Number of successful outcomes / Total number of outcomes
P(7 or 11) = 8 / 36
P(7 or 11) = 2 / 9
So, P(7 or 11) = 2/9.
When rolling two dice, the total outcomes are 6 * 6 = 36.
The combinations of possible outcomes that result in 7 are (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). So, there are 6 ways to get a total of 7.
The combinations of possible outcomes that result in 11 are (5, 6) and (6, 5). So, there are 2 ways to get a total of 11.
Therefore, the total number of successful outcomes is 6 (for 7) + 2 (for 11) = 8.
The probability of rolling a total of 7 or 11 on a pair of number cubes from a single toss is:
P(7 or 11) = Number of successful outcomes / Total number of outcomes
P(7 or 11) = 8 / 36
P(7 or 11) = 2 / 9
So, P(7 or 11) = 2/9.
A six-sided number cube is rolled 30 times and lands on 3 ten times and on 5 eight times. Calculate the experimental probability of landing on a 3. Write your answer in the simplest form of a fraction.
____
____
To calculate the experimental probability of landing on a 3 when rolling a six-sided number cube, we use the formula:
Experimental Probability = Number of successful outcomes / Total number of trials
In this case, the cube landed on 3 ten times out of 30 total trials. Therefore, the number of successful outcomes for landing on 3 is 10, and the total number of trials is 30.
Experimental Probability of landing on 3 = 10 / 30 = 1 / 3
Therefore, the experimental probability of landing on a 3 when rolling a six-sided number cube is 1/3.
Experimental Probability = Number of successful outcomes / Total number of trials
In this case, the cube landed on 3 ten times out of 30 total trials. Therefore, the number of successful outcomes for landing on 3 is 10, and the total number of trials is 30.
Experimental Probability of landing on 3 = 10 / 30 = 1 / 3
Therefore, the experimental probability of landing on a 3 when rolling a six-sided number cube is 1/3.
The experiment involved tossing three coins simultaneously. The experiment was carried out 100 times, and it was noted that three heads occurred 40 times. What is the difference between the experimental probability of getting three heads and its theoretical probability? Write your answer in the simplest form of fraction.
___
___
To find the difference between the experimental probability and theoretical probability of getting three heads when tossing three coins simultaneously, we first need to calculate both probabilities:
Theoretical Probability:
When tossing three coins simultaneously, each coin has two possible outcomes (Heads or Tails). Since there are 3 coins, the total possible outcomes are 2^3 = 8. There is only 1 way to get three heads.
So, the theoretical probability of getting three heads is 1/8.
Experimental Probability:
From the experiment conducted 100 times, it was noted that three heads occurred 40 times. Therefore, the experimental probability of getting three heads is 40/100 = 2/5.
Difference in Probabilities:
The difference between the experimental probability and the theoretical probability is:
2/5 - 1/8 = 16/40 - 5/40 = 11/40
Therefore, the difference between the experimental probability of getting three heads and its theoretical probability is 11/40.

Therefore, the difference between the experimental probability of getting three heads and its theoretical probability is 11/40.
An experiment involves picking a card from the numbers 2, 4, 6, 10. In equation form. What is the probability model for this experiment?
f (x )= ____, where x = 2, 4, 6, 10
f (x )= ____, where x = 2, 4, 6, 10
The probability model for this experiment involves picking a card from the numbers 2, 4, 6, and 10. Since each of these numbers is equally likely to be picked, the probability model can be represented as a probability mass function (pmf) based on a discrete uniform distribution.
The probability mass function f(x) for this experiment where x represents the numbers 2, 4, 6, and 10 can be written as:
f(x) = 1/4, for x = 2, 4, 6, 10
Therefore, the probability model for this experiment is:
f(x) = 1/4, where x = 2, 4, 6, 10
The probability mass function f(x) for this experiment where x represents the numbers 2, 4, 6, and 10 can be written as:
f(x) = 1/4, for x = 2, 4, 6, 10
Therefore, the probability model for this experiment is:
f(x) = 1/4, where x = 2, 4, 6, 10
