Question

A jar contains blue,red and green balls the probability of getting blue ball is(1/3),that of red ball is (1/5). find the number of balls if no of green balls is 14

Answer 1

The probability of no of green ball is
1/14

Answer 2

Answer:

So, The total number of balls in the bag = 30

Step-by-step explanation:

Probability of getting blue ball = 1/3

Probability of getting red ball = 1/5

Since, Sum of probabilities = 1

⇒ Probability of getting green ball = 1 - (1/3 + 1/5)

⇒ Probability of getting green ball = 1 - 8/15

                                                          = 7/15

Number of green balls = 14

So, Numerator in the probability should be equal to number of green balls

So, when multiplying by 2 the denominator becomes 30.

So, The total number of balls in the bag = 30
