Example Question #1 : Understand Probability Of A Chance Event: Ccss.Math.Content.7.Sp.C.5

Select the answer choice that has the greatest probability of occurring. 

Possible Answers:

Using a standard deck of cards, drawing a  

Using a standard deck of cards, drawing a  of spades

Using a standard deck of cards, drawing a  of diamonds 

Using a standard deck of cards, drawing a  of hearts

Correct answer:

Using a standard deck of cards, drawing a  

Explanation:

Probability is represented by a number between  and .

Probabilities are usually written in a fraction form that expresses the likelihood of the event occurring. The greater the fraction—or number—then there is a better probability of the event occurring. 

Each of our answer choices use a standard deck of cards, which has  total cards.

First, let's find the probability of each event:

Drawing a  of hearts: There is only one  of hearts in a standard deck; thus, the probability is:

Drawing a  of diamonds: There is only one  of diamonds in a standard deck; thus, the probability is:

Drawing a  of spades: There is only one  of spades in a standard deck; thus, the probability is:

Drawing a : There are four s in a standard deck; thus, the probability is:

This is the greatest probability and the correct answer.
