A bin contains 8 blue chips, 5 red chips, 6 green chips, and 2 yellow chips.
Question: drawing a red chip, replacing it, then drawing a green chip.

The number of chips of any particular color divided by the total number of chips is the probability. If there is replacement, the total number of chips remains the same.
To find the probability of 2 or more events all occurring, multiply the probability of the individual events.
I hope this helps.
