Answer:

2/5 is the answer for this problem

i hope this answer helps you

Answer 2

Answer:

it is 0

Step-by-step explanation:

now since they are asking about the probability of both blue balls taken out of the bag. we have one blue ball here and suppose you have taken it out from the bag first and it is without replacement. now for the second time you would not have a blue ball to pick so the probability of picking both blus balls is zero.
