There are 18 marbles in a bag, 4 are blue and 14 are yellow. Suppose you take a marble from the bag without looking. Then you take a second marble from the bag without looking. Find the probability that both marbles are blue. Express your answer as a fraction in simplest form.

Step-by-step explanation:

We are given that

Total number of marbles=18

Blue marbles=4

Yellow marbles=14

We have to find the probability that the both marbles are blue.

Probability ,

The probability of getting first blue marble =

It is without replacement.

Now remaining marbles=18-1=17

Blue marbles=4-1=3

The probability of getting second blue marble=

The probability that both  marbles are blue=
