Heather's parents promised her a trip to the roller rink with her friends if she got an A in math. Excited about the idea of roller skating and eating snacks with her friends, she asked her teacher, Mr. Lawrence, if she could do extra credit.

"Of course!" he said enthusiastically.

"Since we've been doing probability lately, I want you to spend an entire day making every choice by chance, and give me your calculations when you're finished."

Heather loved the idea! She thanked Mr. Lawrence and excitedly started planning for the day.

The next morning, Heather put all of her bottoms into one bin, and all of her tops into another. She has 8 bottoms and 5 tops.

What is the probability that Heather will get her favorite shirt?

If 2 of Heather's bottoms are skirts, what is the probability that she will pick one?

Then, Heather had to pack her lunch. 

For her drink, she can have either juice or soda. If there are 6 cans of soda and 8 juice boxes, what is the probability that she will get juice?

For her snack, she can pick two from a selection of carrots, pretzels, and cupcakes. If there are 3 cupcakes, 10 bags of carrots, and 8 bags of pretzels, what is the probability that she picks cupcakes twice?

Heather dumps all of her socks into a bin. She has 9 pairs of socks. She draws the socks one at a time. 

What is the probability of her drawing a sock and then drawing its match?

If 4 pairs of socks are white, 3 are gray, and 2 are blue, what is the probability that she will draw a blue sock and then a white sock?

Heather can choose to either be driven to school by her parents, or ride her bike to school. To decide, she rolls a die. If she gets an even number, she'll use the car. If it's an odd number, she'll use her bike.

What is the probability that she will bike to school?

In class, Heather needs to choose a pencil or a pen to take notes with. She has a 24 pack of colored pencils, 2 normal pencils, and a single pen.

What is the probability that she will draw a colored pencil?

If four of her colored pencils are blue, what is the probability that she will draw a blue colored pencil?
