Question

A box holds 42 pieces of red construction paper and 18 pieces of blue construction paper. A piece of paper is pulled out of the box at random and then placed back in the box. How many times can you expect that a piece of red paper will be pulled out of the box in 110 tries? A. 48 B. 55 C. 60 D. 77

Answer 1

42 red + 18 blue = 60 total.

Chance of red being pulled out once = $\frac{42}{60}$.

$\frac{42}{60} = \frac{7}{10} = 0.777...$

0.777... × 110 = 77 times.

You can expect the red paper to be pulled out 77 times.
