a.
Answer to Problem 43E
Explanation of Solution
Given:
You are given five digits to arrange in the proper order to form the price of a car. If you are correct, you win the car
Let E be the event that you guess the position of each digit correctly.
Since, there is only 1 possible way that all digits are in correct order. So,
Total possible number of ways to choose 5 digits is:
Thus, the probability of winning, given the condition you guess the position of each digit exam is:
b.
To find: the probability of winning, given the condition you know the first digit and guess the positions of the other digits.

Answer to Problem 43E
Explanation of Solution
Given:
You are given five digits to arrange in the proper order to form the price of a car. If you are correct, you win the car
Let E be the event that you know the first digit and guess the positions of the other digits correctly.
Since, there is only 1 possible way that all digits are in correct order. So,
Total possible number of ways to choose the other 4 digits is:
Thus, the probability of winning, given the condition you guess the position of each digit exam is:
