In a box there are 3 red pens, 2 green pens, and 1 blue pen. What is the probability of picking a red pen, replacing it, and then picking a green pen?

1/6

Step-by-step explanation:

Red pens = 3

Green pens = 2

Blue pen = 1

Total = 3+2+1 = 6

Probability of picking a red pen = 3/6 = 1/2

Probability of picking a green pen = 2/6 = 1/3

The probability of picking a red pen, replacing it, and then picking a green pen will be calculated as:

= 1/2 × 1/3

= 1/6
