Question

In a box there are 8 white , 7 purple and 6 yellow balls. One ball is picked at random. What is the probability neither white nor yellow?

Answer 1

Answer:

Step-by-step explanation:

Total no. of balls = (8+7+6) = 21

Let A be the event that ball drawn is neither white nor yellow.

That means event that ball drawn should be purple.

So, no. of favourable outcomes = 7

=> P(A) = No. of favourable outcomes/

Total no. of outcomes

=> 7/21

=> 1/3
