Question

There are 11 people in a group. Four of them are selected to be on a panel. If John is in the group, what is the probability he won't be selected to be on the panel?

Answer 1

`(7)/(11)`

Explanation:

Probability is defined as the likelihood of an event occurring.

-The probability of being selected is :

`P_s=(4)/(11)`

-The probability of not being selected is :

`P_(ns)=1-P_s\\\\=1-(4)/(11)\\\\=(7)/(11)`

Hence, the probability of John not being selected is
`(7)/(11)`
