Question

a box of pencils contains 3 yellow, 4 blue, 1 red, and 2 green. give the probability of pulling out a blue pencil at random as both a fraction and a decimal.

Answer 1

$fraction - \frac{2}{5} \\ decimal - 0.4$

Answer 2

Total number of pencils = 3 + 4 + 1 + 2 = 10

Total number of blue pencils = 4

P(Blue pencils) = 4/10 = 2/5

2/5, when written in decimal, is 0.4

Answer: 2/5 or 0.4
