Question

if one adult is randomly chosen from the group, what is the probability that the adult does not use a cell phone app for shopping and is at least 40 years old?

Answer 1

1/100

Explanation:

The answer is 1/100 because we don't know how many people are in the group but do know that only 1 person has been taken from the group and the probability will be 1 out of how many people are in the group so we just put 100 there as we don't know how many people are in the group.

Ps: Sorry if this is wrong, this is just a guess.
