drawn at random from the bag. Find the probability of
getting a white or a green ball?
OR
A die is thrown once. What is the probability of getting a
number less than 4 ?​

Answer 1

Answer:

P(a white ball or a green ball) = 3/4

OR

P(a number less than 4) = 1/2

Step-by-step explanation:

1. P (a white or green ball) =

            total = 5+8+7 = 20

              => 7+8/20

               = 15/20        

on simplyfing : 3/4

OR

Total = 6

less than 4 = 1,2,3

P (number less than 4) = 3/6 =>1/2
