Question

A card is drawn at random from a well shuffled deck of cards. Find the probability that the card drawn is a card of spade or an ace.

Answer 1

Answer:

Total cards = 52

Favourable cards = 13 + 3 [since 1 is already a spade card]

= 16

Probability

= 16 / 52

= 4 / 13

Answer 2

Answer:

n(S) = 52

n(A) = 13(spades)+ 4(but we should take 3 because one ace is already in spade)

n(A) = 16

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

P(A) = 16/52

P(A) = 4 / 13
