Answer:

here is your answer.

15/21

Answer 2

The required probability is 0.342.

Step-by-step explanation:

Since we have given that

Number of red balls = 6

Number of blue balls = 7

Number of green balls = 8

So, the probability that no ball is red is given by

$\dfrac{^{15}C_3}{^{21}C_3}\\\\=\dfrac{455}{1330}\\\\=0.342$

Hence, the required probability is 0.342.
