What is the probability of a blue marble?
Mikes teacher has three boxes and she puts two red marbles in box A, two blue marbles in box B, and one blue and one red marble in box C.
Part 1 – What is the probability of Mike picking a box so that he gets at least one blue marble?
Part 2 – His teacher now removes one marble from each of the box. What is the probability of Mike getting a blue marble?
PART 1:
1/3 of the time he will get box A with a 0% probability of blue
1/3 of the time he will get box B with a 100% probability of blue
1/3 of the time he will get box C with a 50% probability of blue
1/3 * 0 + 1/3 * 1 + 1/3 * 1/2
= 1/3 + 1/6
= 2/6 + 1/6
= 3/6
= 1/2
Answer:
50%
PART 2:
The probability of box A and B will not change.
1/3 of the time he will get box A with a 0% probability of blue
1/3 of the time he will get box B with a 100% probability of blue
1/3 of the time he will get box C
— 1/2 of the time box C will have 1 red marble (0%)
— 1/2 of the time box C will have 1 blue marble (100%)
1/3 * 0 + 1/3 * 1 + 1/3 (1/2 * 0 + 1/2 * 1)
= 0 + 1/3 + 1/3(0 + 1/2)
= 0 + 1/3 + 1/6
= 2/6 + 1/6
= 3/6
= 1/2
Answer:
Still 50%
