Question 1 of 10

2. Emily orders two cheese pizzas from Toni's Pizza for herself and some friends. However, Toni's Pizza accidentally put some sausage on a few of the slices of each pizza (shown in the pictures as the shaded slices). The sausage is not visible when just looking at the slice of pizza. Given that one of Emily's friends grabs the pizza containing the three slices of sausage, leaving only the other pizza for Emily to choose from, what is the probability that Emily chooses a slice of sausage pizza?

A.\( \frac{1}{4}\)

B.\( \frac{1}{2}\)

C.\( \frac{5}{16}\)

D.\( \frac{6}{16}\)

Our quizzes help students successfully develop the abilities and skills needed to pass the TSI Math test.
These quizzes are about solving problems, so some questions may not be exactly like problems in the book.

For those, you will need to figure out how to adapt what you’ve learned to solve the new and different problems.
If you miss a question, the quiz will show the correct answer, allowing you to self-diagnose your mistake, and then you can try similar problems until you get the questions correct.
