Abox contains 7 plain pencils and 3 pens. a second box contains 3 color pencils and 3 crayonsone item from each box is chosen at random. what is the probability that a pen from the firstbox and a crayon from the second box are selected? write your answer as a fraction in simplest form.

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) =

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) =

P(pen from 1st box and crayon from 2nd box),

= P(Pen) x P(Crayon)

= x

=

a = 11 : 4

b = 38

c = 1 for every 6
