An experiment has four equally likely outcomes: *E*_{1}, *E*_{2}, *E*_{3}, and *E*_{4}.

- a. What is the probability that
*E*_{2}occurs? - b. What is the probability that any two of the outcomes occur (e.g.,
*E*_{1}or*E*_{3})? - c. What is the probability that any three of the outcomes occur (e.g.,
*E*_{1}or*E*_{2}or*E*_{4})?

**a.**

To determine

Find the probability for occurrence of

**Calculation:**

The given experiment has four equally likely outcomes and they are

*Equally likely outcomes*:

If the outcomes are said to be equally likely if they have equal chance of occurrence.

There are total of 4 outcomes and each outcome is equally likely

**b.**

To determine

Find the probability that any two of the outcomes are occur.

**c.**

To determine

Find probability that any three of the outcomes are occur.
