Answer :
Answer:
Probability that Cedric will take the blue and black pen is [tex]\frac{1}{3}[/tex].
Step-by-step explanation:
Total No of pen on Desk = 3
Without replacement means each time next pen is drawn the total no of pen decreases by 1.
So, Probability of Drawing a blue and black pen
= P(Blue) × P(Black) + P(Black) × P(Blue)
= [tex]\frac{1}{3}\times\frac{1}{2}+\frac{1}{3}\times\frac{1}{2}[/tex]
= [tex]2\times\frac{1}{6}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, Probability that Cedric will take the blue and black pen is [tex]\frac{1}{3}[/tex].
