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:

• 8/30
• Green
• 1/6

• Red

• 1/5

• Blue
• 7/30
• Purple
• 2/15

• Yellow

Jenny has a bag full of skittles. The probability of her drawing a blue skittle is 4/30. Predict the number of blue skittles that she would draw if she chose a skittle from the same bag 60 times, replacing each skittle before she would choose again.

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
