© There is a bag filled with 5 blue, 6 red and 2 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?

Sagot :

Answer:  36/169

How to get that answer:

We have 6 red out of 5+6+2 = 13 total.

The fraction 6/13 represents the probability of selecting red at random.

Because the marble is replaced, the probability does not change on the next selection.

The probability of getting two reds in a row is (6/13)*(6/13) = 36/169
