Answer:
Step-by-step explanation:
Probability of drawing a blue marble
= Number of blue Marble/ Total number of marble
= 5 / 4 + 5 + 6
= 5 / 15
= 1/3
Probability of taking another blue marble without replacing the first one
= Number of blue marble - 1 / Total number of marble - 1
= 5 - 1 / 15 - 1
= 4 / 14
= 2/7
