Question

A box contains 4 red pencils, 6 yellow pencils, and 5 blue pencils. What is the probability of randomly selecting a yellow pencil from the box?

Answer 1

Answer:

2/5

Step-by-step explanation:

total outcome = 4+6+5 = 15

no. of favorable outcome = 6

so,p(E) = p(F)/p(T)

= 6/15 = 2/5

Answer 2

The probability of randomly selecting a yellow pencil from the box is 2/5.

Given:-

Number of red pencils in box = 4

Number of yellow pencils in box = 6

Number of blue pencils in box = 5

To Find:-

The probability of randomly selecting a yellow pencil from the box.

Solution:-

We can easily calculate the probability of randomly selecting a yellow pencil from the box by following these simple steps.

As

Number of red pencils in box = 4

Number of yellow pencils in box = 6

Number of blue pencils in box = 5

Total pencils in box = 4 + 6 + 5 = 15

Probability (p) =?

According to the formula of probability,

$p = \frac{desired \: outcomes}{total \: outcomes}$

$p(yellow) = \frac{number \: of \: yellow \: pencils}{total \: pencils}$

$p(yellow) = \frac{6}{15}$

$p(yellow) = \frac{2}{5}$

Hence, The probability of randomly selecting a yellow pencil from the box is 2/5.
