(i) Here, total number of trials = 100 times

Number of heads got (H, H) = 21

∴ P(E) = Number of trials in which two heads occurs/Total number of trials = 21/100

(ii) Total number of trials = 100 times

Number of exactly one head = 55

∴ P(E) = 55/100 = 11/20

(iii) Total number of trials = 100 times

Number of head = 24

∴ Probability = 24/100 = 16/25
