Question

Probabilty?

Answer 1

There is one number in the list of 4 that is prime - the number 7.

The probability of picking 7 out of the 4 choices is `1/4`.

Without putting that card back, we pick another card. There are zero primes out of the three remaining cards, giving `0/3`.

We then multiply the results:

`1/4xx0/3=0`
