Answer :
The estimated probability that at least one student who have NO PETS is 1/4.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Onyx surveys students at his school and finds that 80% have a pet.
He wants to estimate the probability that, if he randomly selected 4 students, at least one student would NOT have a pet.
lets the numbers 1, 2, 3, and 4 represent a student who HAS a pet, and 5 represent a student who does NOT have a pet.
He then has a computer randomly select 4 numbers and repeats this 20 times.
