Hi everyone,

I am having some trouble getting this question, because it is not a style I have done before.

In a large population, people are one of three genetic types: A, B, C: 30% are type A, 60% Type B, and 10% Type C. The probability a person carries another gene miking them susceptible for a disease is 0.05 for A, 0.04 for B, and 0.02 for C.

If ten unrelated persons are selected, what is the probability at least one is susceptible for the disease?

The answer is 0.342
