Answer to Problem 4CFU
The probability that numbers match when a pair of number cubes is thrown provided that their sum is greater than 5is
Explanation of Solution
Given information:
A pair of number cubes is thrown.
Formula used:
Probability of an event Eis
Given an event Q , the conditional probability of event A is
Calculation:
Consider the provided information thata pair of number cubes is thrown.
The probability that numbers match when a pair of number cubes is thrown provided that their sum is greater than 5.
Let A be an event that numbers match and B be an event that sum is greater than or equal to 9.
Recall that probability of an event Eis
Probability that sum is greater than 5,
Probability that numbers match and sum is greater than 5,
Recall that given an event Q , the conditional probability of event A is
The probability that numbers match when a pair of number cubes is thrown provided that their sum is greater than 5.
Thus, the probability that numbers match when a pair of number cubes is thrown provided that their sum is greater than 5 is
