A coin is tossed 40 times and the head appear 15 times . what is the probability of getting a tail ?
Coin tossed 40 times,
no of times head appeared=15
no of times tail will appear=25
probability of getting tail
(in a toss of a coin there are only two outcome;
head and tail)
so if the head is 15 out of 40,the tail is 25)
