30 students in a high school health class are asked to write down what foods they ate last week. Of the 30

students, 10 write tacos, 18 write pizza, and 5 write both tacos and pizza. Using this information, answer

each of the following questions.

Let T be the event that randomly selected student writes tacos and P be the event that a randomly

selected student writes pizza.

What is P (T), the probability that a student writes tacos?

What is P (P), the probability that a student writes pizza?

What is P (T and P), the probability that a student writes tacos and

What is P (Tor P), the probability that a student writes tacos or pizza?

1) P (tacos) = 10/30 = 1/3

2) P (Pizzas) = 18/30 = 3/5

3) P (T AND P) = 5/30 = 1/6

4) P (T OR P) = P (T) + P (P) - P (T AND P)

= 10/30 + 18/30 - 5/30

= 23/30
