Question

determine which numbers could not be used as the probability of an event

determine the number of outcomes in the event. decide whether the event is a simple event or not. a computer is used to select randomly a number between 1, and 9, inclusive. Event B is selecting a number less than 2

Answer 1

SOL:-

1) Probability value must be between 0 to 1. probability values cannot be less than 0 and greater than1.

so, values of less than 0 and   greater than 1 values could not be used as the probability of an event..

2)

Every number from 1 to 9 has equal chance of getting selected.

=> Probability of each number = 1/9.

Selecting a number less than 2 means selecting 1.

Event B has 1 outcome.

This is a

Simple event because B has exactly one outcome.
