Answer ! 20 pts & brainliest a bag contains 15 marbles. the probability of randomly selecting a green marble is 1/5. the probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is 2/25 how many blue marbles are in the bag? a. 2 b. 3 c. 5 d. 6

When we draw with replacement we have independent events and the probability of the conjunction is the product of the individual probabilities.

P(Green first & Blue second) = P(Green first) P(Blue second) = P(Green) P(Blue)

P(Blue) = P(Green first & Blue second) / P(Green) = (2/25)/(1/5) = 2/5

So 2/5 of the marbles are blue, (2/5)(15)=6 marbles

Choice D

question is incomplete.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
