Which expression represents the probability of randomly selecting a green (G) marble, replacing it, and then randomly selecting a red (R) marble? StartFraction 1 over 10 EndFraction (StartFraction 1 over 10 EndFraction) StartFraction 4 over 10 EndFraction (StartFraction 3 over 10 EndFraction) StartFraction 4 over 10 EndFraction (StartFraction 3 over 9 EndFraction) One-fourth (one-third)

Answer 1

Answer:

3/25

Step-by-step explanation:

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(green) = number of green / total = 4/10 = 2/5

We replace it

3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles

P(red) = number of red / total = 3/10

P(green, replace,red) =2/5*3/10 = 3/25
