Question

A bag has 4 red, 5 green and 2 yellow balls. (The balls are identical in all respects other than colour) A ball is drawn from the bag without looking into the bag. What is the probability of getting a non-green ball?




​

Answer 1

Answer:

Total no. of balls = 4+5+2 = 11

Green balls = 5

Red balls = 4

Yellow balls = 2

So, non green balls = (4+2) = 6

Probability of getting a non-green

ball = No. of favourable outcomes / Total no. of outcomes

Probability of getting a non -green

ball = 6/11

Hope it helps you !!

Answer 2

Step-by-step explanation:

Here, number of non-green ball =

4red + 2 yellow=6balls

Total number of balls=4+5+2= 11

p(non green ball)=

num of non-green ball / total number of balls=

6/11..

Hence, the probability of getting a non green ball is 6/11......
