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 Blue ball?
उत्तर
Sample space n(S) = 24
Number of green ball = 24 – (3 + 5)
= 24 – 8
= 16
Let E1 be the event of getting a blue ball
n(E1) = 5
p(E1) = `("n"("E"_1))/("n"("S"))`
= `5/24`
