Answer:
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 = [tex]^{7} C_{4}[/tex] = 35
So,
Probability of getting green, blue, red, and yellow = [tex]\frac{4!}{35}[/tex]
= [tex]\frac{24}{35}[/tex] = 0.69
⇒Probability of getting green, blue, red, and yellow = 0.69
