Answered by Expert Tutors

we want 3 correct out of 5 questions. and each has 5 options.

so the combination will be 5C3.

so the probability of right answer p = 1/5.

and probability of right answer q = 4/5.

it is a binomial question so the probability -

probability = (5 "choose" 3) * (probability correct)(number correct) *(probability incorrect)(number incorrect)

(5C3) * (1/5)3 * (4/5)2

(5*4/2) * (1/125) * (16/25)

= 160/125*25

= 32/625.
