Answer 2

how many blue marbles and how many total?

Answer 3

9 & 22

Answer 4

so
\(\dfrac{9}{22}\)

now when you take the blue out and don't put it back, the total number of outcome changes to 21

Answer 5

so how many yellow marbles?

Answer 6

13?

Answer 7

ok so you have
\(\dfrac{9}{22} * \dfrac{13}{21}\)

Answer 8

now multiple them
