Answer:
21/10
Step-by-step explanation:
Total marbles in the bag = 15
Red marbles in the bag = 5
Probability of picking a red marble the first time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the second time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the third time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble the fourth time = 5/15 .
If you put it back, then everything goes back to the beginning.

.
Probability of picking a red marble the 20th time = 5/15 .
If you put it back, then everything goes back to the beginning.
.
.
.
Probability of picking a red marble the ' Nth ' time = 5/15 .
If you put it back, then everything goes back to the beginning.
Probability of picking a red marble ' N ' times in a row = (5/15)^N.
Probability of picking a red marble 3 times in a row = (5/15) (5/15) (5/15).
Probability of picking a red marble 2 times in a row = (5/15) x (5/15)
= (25/225) = 1/9
= 11.1% (rounded).
You have to make a proportion with a part whole and percent the whole is the money amount the part is the amount of people the percent is well the percent<span />
