Question

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?

Answer 1

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"("E"_2))/("n"("S"))`

= `3/24`

= `1/8`
