Question

A bag contains 3 pink gumballs, 4 red gumballs, and 2 green gumballs. Find the probability that a red gumball is drawn if there are 5 drawings that occur and the gumballs are replaced after each draw. Round your answer to two decimal places.

Answer 1

probability of drawn red balls 0.99

Explanation:

Given data: 3 pink ball

4 red gumballs

2 green gumballs

total number of drawing is 5

probability of drawn red balls is given as

P = 1 - Probability of no red ball drawn

`= 1 - (^4C_0 * ^5C_5)/( ^9C_5)`

`= 1 - (1)/(126)`

`= (125)/(126)`

= 0.99
