Question

a coin toss 3time what is probability of getting all head 2 ) ​

Answer 1

A coin is tossed 3 times..

Sample space of all possible outcomes in 3 different toss is as follows…. H denotes head & T denotes Tail.

H H H

H T T

H H T ……★

H T H …….★

T H T

T H H ……..★

T T H

T T T

Total possible outcomes.. = 8

& favourable outcomes ( getting 2 heads) : 3

Hence, probability( E) = no of favourable outcomes / no of possible outcomes

=> P(E) = 3/8
