Assuming the two events are independent then the second match has the same chance as the first. To findANDprobabilities you should multiply each chance:

Spoiler:

As the outcomes are mutually exclusive we can say thatA box has a group of 24 blocks in it. Some are red, some are yellow, and some are a mixture of the two colors. The probability of drawing a red block is 1/3. The probability of drawing a red and yellow block is 1/12. Determine the number of blocks with yellow on them.

In this case it is consider the chance ofnotgetting a yellow block and take it from 1.

Spoiler:

Multiply the outcome by 24 to get the total number of blocks which are not red/which have yellow on them.
