Respuesta :

3/10 because for RED pens it will be 6/10 multiplied by 5/9 which is 1/3 (last one was for blue i said)

Answer:

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
