Answer:
63/1250
119/2475
Step-by-step explanation:
First we need to figure out the number of yellows
100=28+17+24+y
yellow = 21
Odds of getting a yellow and then a red (with replacement) : (21/100)*(24/100)= 63/1250
Odds of getting a blue into a green (without replacement): (28/100)*(17/99)=119/2475
