Answer 2

Answer:

The probability of red ball is $\frac{4}{9}$.

Given:

There are 9 balls in a black bag 4 are red and 2 are green  

To find:

How many trees would make sure that we at least have a red ball

Solution:

Total number of balls = 9

Total no of red balls = 4

Total no of green balls = 2

Probability of a red ball = $\frac{4}{9}$

Result:

The probability of red ball is $\frac{4}{9}$.
