anyone there

Answer 2

please help

Answer 3

total number of marbles is 15, probability of drawing a blue marble is 5/15, (1/3)
probability of drawing a red marble is 5/15, (1/3)
and probability of drawing a green marble is 5/15, (1/3)
so the probability of drawing a Blue THEN Red THEN green would be 1/3*1/3*1/3

Answer 4

which gives you 1/27
