Answer 17

there are 8 marbles total 3 are red so that is 3/8 and u dont replace so now u got 7 3 are yellow so u have 3/7 now you multiply ill show u\[\frac{ 3 }{ 8 } \times \frac{ 3 }{ 7 }=\frac{ 9 }{ 56 }\]

does 9/56 match one of your answers?

Answer 19

ohh i see! i wasn't subtracting out the one you don't replace. i was doing 3/8 X 3/8 when it was supposed to be 3/8 X 3/7… Thats why i was getting 9/64! lol thank you:)
