Abox contains 6 red pens and 4 blue pens. cory randomly picks a pen from the box and keeps it. then tommy randomly picks a pen from the box. what is the probability both boys will pick red pens?

1/3

Step-by-step explanation:

6 red pens and 4 blue pens, so total is 10 pens

First, Cory randomly picks a red pen from the box and keeps it = 6/10 = 3/5

Then Tommy randomly picks another red pen from the box = 5/9

The probability both boys will pick red pens = 3/5 x 5/9 = 3/9 = 1/3
