Answer:
It would be 0.09
Step-by-step explanation:
First, note the original Probability for picking a blue marble in the first try:
0.3
Now, if this were to happen again, knowing that no marbles would be taken out, it would be another chance of 0.3 for Aron to pick up a blue marble on his second pick up.
Due to these being independent events, you can do:
0.3*0.3 = 0.09
To get your answer, 0.09.
Answer:
27/90 = 3/10
Step-by-step explanation:
Calculate the probability that neither is blue
7/10 * 6 / 9
63/90
Now the remainder of the choices are what the probability is when both are blue
1 - 63 / 90
27/90 is the probability of choosing 2 blues.
