Three fair quarters are tossed, and a tail appears on at least one of them. what is the probability that at least one head appears? express your answer as a common fraction

Probability that at least one head appears is

Step-by-step explanation:

Given : Three fair quarters are tossed, and a tail appears on at least one of them.

To find : What is the probability that at least one head appears?

Solution :

When three fair quarters are tossed the sample form is

According to question,

In a sample space a tail appears on at least one of them.

i.e. Total outcomes is

Favorable outcome is getting at least one head appears

i.e. Favorable outcome is

Probability that at least one head appears is

Therefore, Probability that at least one head appears is

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
