From a pack of 52 cards , one card is drawn at random . What is the probability that he card drawn is a ten or a

spade ?


Options:
A .  `4/13`
B .  `1/4`
C .  `1/13`
D .  `1/26`
Answer: Option A

Here , n(S) = 52.

There are 13 spades (including  one ten ) and there are 3 more tens .

Let  E = event of getting a ten or a spade.

Then ,  n(E) = (13 + 3) = 16.

`:.`      P(E) = `  (n(E))/(n(S)) = 16/52 = 4/13`
