Probability of an event = No. Of favourable occurrences / Total no. Of occurrences of all possible events Let 'n' be the total no. Of times the coin is tossed. Given probability of success of a head appearing = 0.4 Given the no. Of times 'head' appeared = 24 So, 0.4 = 24 / n n = 24 / 0.4 So, n = 60.

Answer of n =60, since p(h)=0.4 , and n=24= total no of head appearances, then we get equation , 0.4 n = 24 / n, solving fr n total appearances 0.4 n =24 .. eq (1) or 4n =240 or n=240/4=60 total appearances , is the required answer .. Dr K S Velmurugan Quantitative methods Teacher Pondicherry
