A certain coin will turn up heads with probability p and tai

A certain coin will turn up heads with probability p and tails with probability 1 p, where 0 < p < 1. The coin is tossed repeatedly until it turns up heads, and the number of tosses is recorded.

(a) Let S be the sample space of the experiment. Write down S. This sample space is not a finite set.

Solution

result will be tails evertime till head shows up and experiment is stopped..

sample space-(H,TH,TTH,TTTH,TTTTH,TTTTTH...............}
