I am not sure how to do this, just guesssing.

A couple has a 2/3 probability of passing on brown eyes to their children. If they have four children,

what is the probability that none of the children will have brown eyes?

A) 8/27 B) 1/27 C) 1/81 D) 16/81

Would I multiply 2/3^4 thus my answer is D) 16/81
