QUESTION:

Computer Ownership At a local university 54.3% of incoming first-year students have computers. If 3 students are selected at random, find the following probabilities.

a. None have computers.

b. At least one has a computer.

c. All have computers.

Step 1 of 4

Three students are chosen at random, let

$$A_{i}$$ be the event that i-th student has a computer

(When i is used like this, the statement is true if i is replaced with any number out of 1,2,3)

Because of randomness all $$A_{i}$$ are independent and have the dame probability $$P\left(A_{i}\right)=0.543$$.
