Abag contains one red pen, four black pens, and three blue pens. two pens are randomly chosen from the bag and are not replaced. to the nearest hundredth, what is the probability that a black pen is chosen first and then another black pen is chosen?

Probability is 0.21

Step-by-step explanation:

A bag contains red pen = 1

                  Black pen    = 4

                    Blue pens  = 3

Total pens in the bag =    1 + 4 + 3 = 8 pens

Two pens are chosen from the bag without replacement.

The probability that first pen is black pen = P₁ =  

The probability that second pen is black  = P₂ =  

Probability =   ×  

                  = 0.214285 ≈ 0.21

The probability that a black pen is chosen first and then another black pen is chose is 0.21.
