Total no.of out comes = 15
∴n(S) = 15
Let `E` be event of getting a card bearing prime no
No.of prime numbers in the cards = 6 [2,3,5,7,11,13]
∴n(E) = 6
P(E) = n(E)/n(S)
= 6/15
= 3/5
∴The probability that the card drawn bears a prime no is 3/5
∴n(S) = 15
Let `E` be event of getting a card bearing prime no
No.of prime numbers in the cards = 6 [2,3,5,7,11,13]

= 6/15
