Liam Galvan · Answer 1

1st box ... 2 plain pencils ... 6 pens ... total of 18 writing utensils

2nd box ... 5 color pencils ... 3 crayons ... total of 8 writing utensils

probability of picking a pen from 1st box is 6/18 reduces to 1/3

probability of picking a crayon from the 2nd box is 3/8

And since these are both independent events, the probability of both happening can be found by multiplying the independent probabilities.

1/3 * 3/8 = 3/24 which reduces to 1/8 <==
