Question

From a pack of cards find the probability of drawing a spade card or a diamond card.

Answer 1

Final Answer : 1/2

Steps:
1) Total no. of Cards ,n(S) = 52

No. of spade Cards = 13
No. of Diamond Cards = 13

Then, total no. of spade and Diamond Cards,n(E) = 13 +13 = 26

Probability getting either Spade or Diamond Card = n(E) / n(S)
= 26 /52
= 1/2

Hence, Probability of drawing a spade card or a diamond Card is 1/2 .
