Answer:
3/50
Step-by-step explanation:
There are 5 + 4 + 2 + 6 + 3 = 20 marbles in the bag
P(draw a black) = 6/20 = 3/10
If the black marble is replaced, then there are 20 marbles in the bag again.
P(draw a blue) = 4/20 = 1/5
P(draw a black and blue with replacement) = (3/10)(1/5) = 3/50
200,000,000 that your answer
Probability=number of specific outcomes/number of possible outcomes...
P(B)=B/T=12/(12+12+8)
P(B)=12/32
P(B)=3/8
