Question

men and women appeared in an interview for two vaccine in the same post the probability of man selection is 1 / 4 and that of the women selection is 1/3
what is the probability that none of them will be selected

Answer 1

Answer:

The probability of the selection of the man is 1/4

Also,the probability of selection of woman is 1/3

So, from that we know that there are four men and three women in total.

As the total probability is 1,

Probability of non-selection of that particular man(or other men) : 3/4

Probability of non-selection of that particular woman(or other women) : 2/3

Probability of none of them selected will be

3/4 * 2/3 =1/2
