Explanation Given Information: The number of participants in the sample is n = 5 and the number of male and female participants are equal. Formula used: In n independent Bernoulli trials the probability of x successes is calculated using the formula, P ( X = x ) = C ( n , x ) p x q n − x Where p is the probability of success and q = 1 − p . Calculation: Consider the Bernoulli trials where in each trial a participant is selected and it is observed that if the participant is a male or a female. The “success” in these trials will be the selection of a male. Calculate the probability of selecting a male participant as: The number of male participant is equal to the number of female participant. Thus, the probability of selecting a male participant is p = 0.5 and female is q = 0.5 . Then the probability that at least 2 will be males implies that either 2 or more than 2 of the participant will be males. Since the sum of probabilities is 1 the probability of at least 2 male can be computed as, P ( X ≥ 2 ) = 1 − [ P ( X = 0 ) + P ( X = 1 ) ] The probability for X = 0 and X = 1 can be computed using the formula, P ( X = x ) = C ( n , x ) p x q n − x Compute the value of P ( X = 0 ) as follows: P ( X = 0 ) = C ( 5 , 0 ) ( 0
