Question

A piece of paper is randomly selected from a stack that contains 15 small, 44 large, and 20 extra large pieces.

Which statement is true?

P(large)≈0.75

P(small)≈0.81

P(extra large)≈0.25

Answer 1

P(large)≈ 44/79 = 0.55

P(small)≈ 0.19

P(extra large)≈0.25

Answer is
P(extra large)≈0.25

Answer 2

Answer: P(extra large)≈0.25

Explanation:

Given: Number of small pieces of paper = 15

Number of large pieces of paper = 44

Number of extra large pieces of paper = 20

The total number of pieces of paper =
`15+44+20=79`

Now, the probability of selecting a small piece of paper is given by:-

`P(small)=\frac{\text{15}}{79}=0.18987341772\approx0.19`

The probability of selecting a large piece of paper is given by:-

`P(large)=\frac{\text{44}}{75}=0.556962025316\approx0.56`

The probability of selecting a extra large piece of paper is given by:-

`P(extra\ large)=\frac{\text{20}}{79}=0.253164556962\approx0.25`..........................which is the true statement among all.
