Question

A coin is tossed, and the random variable X is the number of heads that appear. Use H to represent the head and T to represent the tai

Answer 1

When a coin is tossed the sample space S= { H, T }

Since X represent the number of heads that can occur, X can take the value of 0 or 1

so, the p( x=0 ) = 1/2

p ( x=1 ) = 1/2

Therefore, the probability distribution is give by

x 0 1

p(x) 1/2 1/2
