Example Question #2 : Understand Probability Of A Chance Event: Ccss.Math.Content.7.Sp.C.5
Select the answer choice that has the greatest probability of occurring.
Using a standard deck of cards, drawing a Queen
Using a standard deck of cards, drawing red
Using a standard deck of cards, drawing an of spades
Using a standard deck of cards, drawing a black
Using a standard deck of cards, drawing a Queen
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 red : There are two red
s in a standard deck; thus, the probability is:
Drawing an of spades: There is only one
of spades in a standard deck; thus, the probability is:
Drawing a black : There are two black
s in a standard deck; thus, the probability is:
Drawing a Queen : There are four Queens in a standard deck; thus, the probability is:
This is the greatest probability and the correct answer.
Example Question #11 : Understand Probability Of A Chance Event: Ccss.Math.Content.7.Sp.C.5
Select the answer choice that has the greatest probability of occurring.
Using a standard deck of cards, drawing a face card
Using a standard deck of cards, drawing a red card
Using a standard deck of cards, drawing a number card
Using a standard deck of cards, drawing a black card
Using a standard deck of cards, drawing a number card
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 black card: Half of the cards in a standard deck are black; thus, the probability is:
Drawing a red card: Half of the cards in a standard deck are red; thus, the probability is:
Drawing a face card: There are face cards in a standard deck (
Jacks,
Queens,
Kings) ; thus, the probability is:
Drawing a number card : In a standard deck, the numbers are used, and each number has four suites, which equals
numbered cards; thus, the probability is:
This is the greatest probability and the correct answer.
Example Question #12 : Understand Probability Of A Chance Event: Ccss.Math.Content.7.Sp.C.5
Select the answer choice that has the lowest probability of occurring.
Using a standard deck of cards, drawing a red King
Using a standard deck of cards, drawing the King of Hearts
Using a standard deck of cards, drawing a King
Using a standard deck of cards, drawing a black King
Using a standard deck of cards, drawing the King of Hearts

Drawing the King of Hearts : There is only one King of Hearts in a standard deck; thus, the probability is:
This is the least probability and the correct answer.
Example Question #51 : Statistics & Probability
If John were to roll a die times, roughly how many times would he roll a
A die has sides, with each side displaying a number between
.
Let's first determine the probability of rolling a after John rolls the die a single time.
There is a total of sides on a die and only one value of
on one side; thus, our probability is:
This means that roughly of John's rolls will be a
; therefore, in order to calculate the probability we can multiply
by
—the number of times John rolls the die.
If John rolls a die times, then he will roll a
roughly
times.
