an experiment consists of 4 tosses of a coin.denoting the outcomes HHTH,THTT,..and assuming that all 16 outcomes are equally likely, find the probability distribution for the total number of heads.

Denote all the outcomes. Count the number of of outcomes with 0 heads, 1 head, 2 heads, 3 heads and 4 heads. Graph the probability distribution from that data.
