Solution
Coin tossed 40 times,
no of times head appeared=15
no of times tail will appear=25
probability of getting tail
=25/40
=5/8
=.625
(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)
no of times head appeared=15
no of times tail will appear=25
probability of getting tail
=25/40
=5/8
=.625
