Question

300300 students in a high school freshman class are surveyed about what kinds of pets they have. Of the 300 students, 200 have a dog, 180 have a cat, and 150 have a cat and a dog. Using this information, answer each of the following questions.

Answer 1

Probability P(D and C) is (C) 1/2.

What is probability?

• Probability is the branch of mathematics that deals with numerical descriptions of how probable an event is to occur or how likely it is that a claim is true.
• The probability of an event is a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.

To find the probability P(D and C):

According to the task content;

• The total number of students in the class is; 300.
• The number of students who have a cat and a dog is 150.

On this note, the probability, P(D and C) is given as;

• P(D and C) = 150/300 = 1/2

Therefore, probability P(D and C) is (C) 1/2.
