Question

Tom has 12 cards with the numbers 1 to 12 on them.
He selects one card at random.

Find P(prime number).

Answer 1

Answer:

1 / 4

Step-by-step explanation:

Given that :

Cards numbered 1 - 12

Multiples of 4 = 4, 8, 12

Probability = required outcome / Total possible outcomes

P(picking a multiple of 4)

:

Required outcome = multiples of 4 = 3

Total possible outcomes = 12

Hence,

P(picking a multiple of 4) = 3 / 12 = 1/4

Answer 2

Answer:

5/12

Step-by-step explanation:

total number of prime numbers from 1 to12 = 5

so 5/12
