Answer:
185 marbles
Step-by-step explanation:
Probability of 1/5 of white marbles means 1/5th of the total number of marbles is white.
Hence, the total marbles is 5 times 37 of white marbles.
We simply multiply 37 and 5 to get:
37 * 5 = 185 marbles
Checking:
If there is 185 marbles in total and 37 is white, the probability of white is
37/185 = 1/5
So correct.
