Best answer
Given number of trials = 500 From the given table it is clear that, Number of outcomes of two heads (HH) = 105 Number of outcomes of one head (HT or TH) = 275 Number of outcomes of no head (TT) = 120 (i) Probability of getting two heads = frequency of getting 2 heads/ total number of trials = 105/500 = 21/100 (ii) Probability of getting one head = frequency of getting 1 heads/ total number of trials = 275/500 = 11/20 (iii) Probability of getting no head = frequency of getting no heads/ total number of trials = 120/500 = 6/25
