Sample space ={5G, 2Y, 8R, 3P} =18 POSSIBLE OUTCOME

1st draw: P(R) = 8/18 = 4/9 = 0.444
2nd draw (no replacement, means already one Red is picked up, so the sample space has been reduced): P(another one more RED) = 7/17 =0.411

Miguel has 225 baseball cards. He plans to keep 75 cards and give the rest to his friends.
jenyasd209 [6]

yes and no answer+the math:

1) yes
2) yes

1) so if you take 255-75 you get 180 now keep that in mind for number 2, when you divide 180 by 6 you will get 30 so we can give 30 cards to everyone

2) remember the 180? were using it again. if you do 180 and divide that by 4 you get 45 so we can give 45 cards to everyone.

hope this helps!
