a bag of 75 marbles has 8 white, red , and 20 green marbles. the remaining marbles are clear. What is the chance of picking a clear marble.

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
