प्रश्न

There are 24 balls in a pot. If 3 of them are Red, 5 of them are Blue and the remaining are Green then, what is the probability of picking out a Red ball?

बेरीज

उत्तर

Sample space n(S) = 24

Number of green ball = 24 – (3 + 5)

= 24 – 8

= 16

Let E2 be the event of getting a red ball

n(E2) = 3

p(E2) = n(E2)n(S)

= 324

= 18
