Answer:
Step-by-step explanation:
Consider the provided information.
Bag contains 8 red marbles, 6 white marbles, and 8 blue marbles.
Total number of marbles = 8+6+8=22
The probability of getting a red marbles: 8/22
The probability of not getting a red marbles: 14/22
Now consider the part A:
We need to find probability that all the marbles are red if 4 marbles drawn.
The probability that all marbles are red is:
Hence, the probability that all marbles are red is 0.009569
Part B
Find the probability that exactly two of the marbles are red.
The probability that exactly 2 marbles are red is:
Hence, the probability that exactly two red marbles is 0.0581
Part C
Now find the probability that none of the marbles are red.
The probability that none of the marbles are red is:
Hence, the probability that none of the marbles are red is 0.1368
