Number of times Two heads occurred: 112


Number of times One head occurred: 160


Number of times No head (zero head) occurred: 128


Probability P()=


(i). Let p(H1) be probability of getting Two heads


P (H1) =


P (H1) = = 0.28


(ii). Let p(H2) be probability of getting One head


P (H2) =


P (H2) = = 0.4


(iii). Let p(H3) be probability of getting No head


P (H3) =


P (H3) = = 0.32
