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.
