Answer:
<h2>4/9</h2>
Explanation:
Given;
As given, probability of obtaining a male is = 2/3;
sexes of each individual are independent.
Probability of obtaining two males in cluster of three is;
2/3* 2/3= 4/9
So the probability of obtaining two males in cluster of three is= 4/9
There are three ways of calculation.
