Suppose that in a certain population of lizards under a particular set of environmental conditions, the probability of obtaining a male is 2/3. Assume that the sexes of each individual are independent. What is the probability of obtaining exactly two males in a clutch of three? (Note: there are three ways of obtaining exactly two males, depending on birth order)

4/9

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.
