A bag contains 7 marbles: one each of red, orange, yellow, green, blue, violet, and white. A child randomly pulls 4 marbles from the bag. What is the probability that the marbles chosen are green, blue, red, and yellow? Round your answer to the nearest hundredth.

Probability of getting green, blue, red, and yellow = 0.69

Step-by-step explanation:

Given - A bag contains 7 marbles: one each of red, orange, yellow, green, blue, violet, and white. A child randomly pulls 4 marbles from the bag.

To find - What is the probability that the marbles chosen are green, blue, red, and yellow?

Proof -

Given that,

A bag contains 7 marbles: one each of red, orange, yellow, green, blue, violet, and white.

i.e.

All the outcomes are equally likely.

So,

The child can choose the 4 marbles in 4! ways.

And

Total number of ways = = 35

So,

Probability of getting green, blue, red, and yellow =

                                                                                   = = 0.69

⇒Probability of getting green, blue, red, and yellow = 0.69
