Question

A coin is tossed 20times and it showed tail 12 times find the probability of getting the head
​

Answer 1

Answer :

Given : Total no. of times coin is tossed - 20

Total no. of times it shows tail - 12

To find : Total no. of times it show head ?

Soln : P(E) = Desirable outcome of an event / Total outcome of an event

20 = Head + Tail

20 = Head + 12

Head = 8

P(E) = 8/20

P(Total no. of times head ) = 2/5
