Taylor surveys students in one grade level who own at least one pet. She finds that 50% of the students surveyed own 2 pets, 3 s

Rasek [7]

Answer:

Step-by-step explanation:

We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population

That means total number of students being surveyed is 13+13=26 students

Then we work out the probability

P(One pet) = 8/26 = 4/13

P(Two pets) = 1/2

P(Three pets) = 3/26

P( Four pets) = 2/26 = 1/13

The probability distribution is shown in the table below. Let be the number of pets and is the probability of owning the number of pets
