Ajar has five red marbles in at 10 blue ones if you randomly pick a marble without replacing it and then select another what is the fractional probability of getting two red?

2/21

Step-by-step explanation:

We know that there is a jar which has 5 red marbles and 10 blue marbles in it.

We are to find the fractional probability of getting two red marbles if we randomly pick a marble and then without putting it back we pick another one.

P (getting red marble on first time) =

P (getting red marble on second time) =

P (getting two reds) =
