(a)
Answer to Problem 7.8E
Explanation of Solution
Calculation:
The selection of each digit has a probability of 1 in 10 so the probability of selecting of foru numbers (any combination) is
Every number has the same probability of being selected.
(b)
To Explain: the probability for 9999 and 2873.
(b)
Explanation of Solution
Most people will be thinking that the less likely to be elected in 9999, because the probability of a number with all the same digits is being selected less than the number to be chosen with four different digits. Thus the most people will favour 2873.
