Explanation of Solution
Given:
Concept used:
Binomial probability refers to the probability of exactly
If the probability of success on an individual trial is
Then the binomial probability is:
The probability is minimum
If
At least
At most
Calculation:
The probability of all carrying the disease is:
Hence, the probability of all carrying the disease is
