SOLUTION
Now the jar contains 6 red marbles and 27 blue marbles
Total number of marbles is

Now taking two red marbles at random means the first marble is red and the second marble is red.
Probability that the first marble is red is

After taking the first red marble, we will have 5 red marbles remaining and a total of 32 marbles remaining
So probability of picking the second marble is

So probability both marbles are red means the first is red and the second is red.
And here means we have to multiply, this becomes

Hence the answer is
