In a game, 20 small squares of paper are numbered 1 through 20. If Egan randomly selects 1 piece of paper, what is the probability that he will select a multiple of 4?

1/4

Step-by-step explanation:

Probability is essentially (# times a specific event occurs) / (# times any general event occurs).

Here, the "specific event" is selecting a multiple of four. The multiples of 4 from 1 to 20 are: 4, 8, 12, 16, and 20 - there are 5 of these. So, the number of times the specific event can occur is 5.

The "general event" is selecting any number out of the 20. Since there are 20 numbers, then there are 20 ways that a general event occurs.

So, the probability is 5/20 = 1/4.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
