what is the experimental probability of drawing a blue marble then  a red marble and then  a green marble 

what is the experimental probability that jim does not draw a red marble

mathmate · Answer

Number of red marbles = number of green marbles = number of blue marbles = 15
Total number of marbles = 15
Draws with replacement

P(R)=P(G)=P(B)=$\frac1 3$

To get BRG in order is a three step experiments in which all steps are independent

P(BRG in order)=P(B)*P(R)*P(G)=$\frac1 3$*$\frac1 3$*$\frac1 3$=1/27
