Correct Question

A local coffee house surveyed 317 customers regarding their preference of chocolate chip or cranberry walnut scones . 150 customers prefer the Cranberry Walnut Scones . 81 customers who responded were males and prefer the Chocolate Chip Scones . 172 female customers responded . Find the probability that a customer chosen at random will be a male or prefer the Chocolate Chip Scones .

A) 25.6%

B) 24.1%

C) 72.9%

D) 98.4%

C) 72.9%

Step-by-step explanation:

From above question, we were given the following parameters.

Total number of customers = 317 customers

150 customers prefer the Cranberry Walnut Scones .

Since the number of Customers who prefer Cranberry Walnut Scones is given, the number of Customers who prefer Chocolate Chip Scones is calculated as

317 - 150 = 167

The number of Customers who prefer

81 customers who responded were males and prefer the Chocolate Chip Scones .

172 female customers responded

Since the number of female customers who responded were given, the number of male customers who responded is calculated as

317 -172 = 145

The probability that a customer chosen at random will be a male or prefer the Chocolate Chip Scones will be calculated as

The number of customers who prefer Chocolate chip scones + The number of males who responded - The number of customers who are males and prefer Chocolate chip scones

167 + 145 -81

= 312 - 81

= 231

= 231/317 × 100

= 72.87%

Approximately = 72.9%

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
