Question

From a group of 2 boys and 2 girls , two children are selected at random . what is the sample space represnting the event . Find the probability that one boy and one girl is selected

Answer 1

Sample space =4
No of boys=2
Probability of a boy getting selected =2/4=1/2
Probability of a girl getting selected =2/4=1/2

Answer 2

Since there are 2 boys and 2 girls thus sample space is 4
the probability that one boy and one girl is selected are--

Over here there are 2 events thus the changes are 2 out of 4

2/4=1/2
thus there are 1/2nchances that there are 2 boys and 2 girls selected
