Question

A fair coin is tossed two times in succession. The equally likely outcomes is ( HH,HT,TH,TT). Find the probability of getting exactly zero heads.

Answer 1

There is only one outcome in the four possible outcomes that has zero heads: TT (tails, tails).

Since all outcomes are equally likely, the probability of getting exactly zero heads is 1 out of 4.

Therefore, the probability of getting exactly zero heads is 1/4.
