Question

probability question ? what is probability of getting head first time head second time and head third time? in fair coin.

Answer 1

These are three INDEPENDENT EVENTS, and to find the probability of these happening together, you must multiply the probability of each.

Answer 2

P(head first time) = 1/2
P(head second time) = 1/2
P(head third time) = 1/2

P(all three) = 1/2 * 1/2 * 1/2

Answer 3

its simply P(head) x P(head) x P(head)
