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

Answer:

$\frac{7}{11}$

Step-by-step explanation:

Probability is defined as the likelihood of an event occurring.

-The probability of being selected is :

$P_s=\frac{4}{11}$

-The probability of not being selected is :

$P_{ns}=1-P_s\\\\=1-\frac{4}{11}\\\\=\frac{7}{11}$

Hence, the probability of John not being selected is $\frac{7}{11}$
