Example Question #51 :Statistics & Probability
Select the answer choice that has the greatest probability of occurring.
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 face card
Using a standard deck of cards, drawing a number card
Probability is represented by a number between
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
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
Drawing a number card : In a standard deck, the numbers
这是最大的概率和正确的nswer.
Example Question #52 :Statistics & Probability
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 a King
Using a standard deck of cards, drawing the King of Hearts
Using a standard deck of cards, drawing a black King
Using a standard deck of cards, drawing the King of Hearts
Probability is represented by a number between
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
First, let's find the probability of each event:
Drawing a black King: There are two black Kings in a standard deck; thus, the probability is:
Drawing a red King: There are two red Kings in a standard deck; thus, the probability is:
画一个国王:有四王一个标准deck; thus, the probability is:
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.
