Question

Probability is a measure of how likely an event is to occur. Choose the probability that best matches each of the following statements: (a) This event is impossible: [ Select ] (b) This event will occur more often than not, but is not extremely likely: [ Select ] (c) This event is extremely unlikely, but it will occur once in a while in a long sequence of trials: [ Select ] (d) This event will occur for sure: [ Select ]

Answer 1

(a) 0

(b) 0.6

(c) 0.01

(d) 1

Explanation:

Given

Probabilities: 0, 0.01, 0.3, 0.6, 0.99, and 1 ---> Missing information

Required

Match the probabilities with appropriate values

(a) Impossible:

An impossible event will always have a probability of 0

(b) Occurrence is more often than not, but not extremely likely:

An event that will occur more often than not will have a probability greater than 0.5 but less than 1

However, if the likelihood is not extremely likely, the probability will be closer to 0.5 and 1.

The probability that matches this description is 0.6

(c) Occurrence is extremely unlikely, but will occur once in a while

An event that is extremely unlikely will have a value greater than 0 and the value will be very close to 0.

The probability that matches this description is 0.01

(d) A certain event:

A certain event has a probability of 1
