Question

Cards numbered between 3 and 40 are placed in a bag. A card is taken out. What is the probability that the card is a prime number.

Answer 1

Answer:

11/38

Step-by-step explanation:

Let 'S'be the sample space

n(S)=38

Let 'A'be the event of selecting prime number card

A={3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37}

n(A)=11

P(A)=n(A)/n(S)

=11/38
