+273 I really hate that it's these three questions, but they all go together, and they all stem from the one explanation!! Sorry again!
+129852 Don't worry about it, LF......!!!
90. We have 40 marbles....and we are drawing with replacement.......
Blue then Red =
(4/40) * (12/40) =
(1/10) * (3/ 10)
3 / 100
91. Two yellows = (8/40) * (8/40) = (1/5) * (1/5) = 1/25
92. Not a green on the first pick...= 24/40 = 3 / 5
+273 Thank you so much! I just wish I had been able to write it out! :)
