Lana has a bowl of marbles the bowl contains 5 green marbles, 3 red marbles and 2 blue marbles from the bowl one at a time. What is the probability that lana will select a green marble first, replace the marble, then select a red marble

3/20

Step-by-step explanation:

5 green marbles, 3 red marbles and 2 blue marbles from the bowl = 10 marbles

P (green) = green/total = 5/10 = 1/2

Replace

5 green marbles, 3 red marbles and 2 blue marbles from the bowl = 10 marbles

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

P (green, replace, red) = 1/2 * 3/10 = 3/20
