A box contains 6 red balls, 7 green balls and 5 blue balls. each ball is of a different size. the probability that the red ball being selected is the smallest red ball, is op 1: 1/

Answered by admin @ 13/08/2021

Answer:

1/6

Step-by-step explanation:

It is given that there are 6 red balls, 7 green balls and 5 blue balls. Therefore, the total number of balls = 18.

P(red ball) = 6/18.

P(smallest ball and red ball) = 1/18

Because out of all the 18 balls, only one is the smallest red.

Therefore, P(The smallest red ball is picked | a red ball is picked) = P(smallest ball and red ball)/P(red ball)

= $\frac{\frac{1}{18}}{\frac{6}{18}}=\frac{1}{6}$
