Explanation / Answer
A) The probability of picking a blue marble on the first pick, replacing it, then picking a red marble on the second pick
=(2/5)*(3/5) =6/25
B) The probability of picking a blue marble on the first pick, keeping it in your hand, then picking a blue marble on the second pick =(2/5)*(1/4) =1/10
C) The probability of selecting a red marble on the first pick, not replacing it in the bag, and selecting a red marble on the second draw =(3/5)*(2/4) =3/10
D) probability of selecting a red marble, putting it back in the bag, then selecting a red marble on the second pick
=(3/5)*(3/5) =9/25
E) probability of selecting a blue marble on the first pick =2/5
F) probability of selecting a red marble on the first pick =3/5
