Introduction to Probability Review

Jenny has a bag full of Skittles. She has 4 blue Skittles, 8 yellow Skittles, 6 green Skittles, 5 purple Skittles, and 7 red Skittles. What is the probability of getting each different color of Skittle

Match the color to its correct probability:

• 1/5

• Green

• 8/30

• Blue

• 2/15

• Purple

• 1/6

• Yellow

• 7/30

• Red

Jayden randomly picks Sour Patch kids out of his box to see what color they are. He puts each one back in the box before he picks another. There are a total of 3 red, 5 yellow, 7 blue, and 5 orange Sour Patch Kids. What is the probability, in decimal form, that the first Sour Patch Kid Jayden picks will be a blue or a yellow.

• 0.45

• 0.6

• 0.35

• 12/20

The Spinner shown is divided into 6 equally sized sections. Suppose you spun the spinner 96 times. Predict the number of times you would land on an even number.

probability describes how likely an event is to occur. ​ probability is the actual result of the experiment. Both of these probabilities will ​ be the same.

• Theoretical

• Experimental

• Sometimes

• Always

• Never

• Hypothetical

Diego and Laila were playing a game of life. The spinner is split into 10 congruent sections. If Diego spins the spinner 30 times, how many times should the spinner theoretically land on 7.

• 3/30

• 1 time

• 7 times

• 3 times

The Spinner on the left has 6 congruent sections. What is the probability of spinning a number less than 5.

• 2/3

• 4

• 1/3

• 5/6

Joccelyn has a giant T-shirt cannon at the Super Bowl. The table shows the number of T-shirts she has of each color. The shirts are put into the cannon at random. Based on the table, which statement is true?

• The shirt color least likely to come out of the cannon first is Gold

• The shirt color most likely to come out of the cannon first is Black

• The first shirt is half as likely to be red than white

• The first shirt is twice as likely to be Black than Red
