Answer:
[tex]\frac{3}{20}[/tex]
Step-by-step explanation:
Box 1:
Number of pens = 3
Total number of items = pencils + pens = 7 + 3 = 10
Probability that a pen will be picked, P(Pen) = [tex]\frac{3}{10}[/tex]
Box 2:
Number of crayons = 3
Total number of items = color pencils + crayons = 3 + 3 = 6
Probability that a crayon will be picked, P(Crayon) = [tex]\frac{3}{6}[/tex]
P(pen from 1st box and crayon from 2nd box),
= P(Pen) x P(Crayon)
= [tex]\frac{3}{10}[/tex] x [tex]\frac{3}{6}[/tex]
= [tex]\frac{3}{20}[/tex]
