Answer: 3/20
Explanation:
In that list, the numbers 2,3,5 are prime. The value 1 is not prime.
The probability of picking a prime number in that list is 3/5 because we have three prime numbers out of five total.
After not putting that card back, we have 5-1 = 4 cards left. The probability of picking "1" is 1/4 since there's one card we want out of four cards left over.
Multiply the fractions mentioned:
(3/5)*(1/4) = (3*1)/(5*4) = 3/20
