In a diving competition, each diver has a 25% chance of a perfect dive. The first perfect dive of the competition, but no subsequent dives, will receive a perfect score. If Janet is the third diver to dive, what is her chance of receiving a perfect score? (Assume that each diver can perform only one dive per turn.) Choose the correct choice from the following choices:
A) 1/5
B) 1/15
C) 4/25
D) 9/64
E) 61/125
Probability = Favourable Outcomes / Total Outcomes = 1 - (Unfavourable Outcomes / Total Outcomes)   Given:Probability of Perfect dive = 0.25 = 25/100 = 1/4   i.e. Probability of Non-Perfect dive = 0.75 = 75/100 =3/4   The probability of Janet to dive and get a perfect score depends on that other other previous two dives must be Imperfect   Method-1:   i.e. Probability of First two being Imperfect and Third being Perfect dive = (3/4)*(3/4)*(1/4) =9/64   9/64
