1. Draw a Venn diagram to represent this situation. the probability that I use my laptop on any given day is 90%. The probability that I use my ipad on a given day is 55%. The probability that I use them both is 50%. Draw the Venn diagram, label it and fill in all spaces.

Then answer the following questions:

1. What is the probabilty that I just use my iPad, not my laptop?

2. What is the probability that I use neither device?

3. What is the probabilty that I use my laptop, given that I am using the iPad?

2. I have 10 cards in a deck, numbered 1 through 10. I draw two cards without replacement and notice if the number is odd or even.

Draw a tree diagram to represent this situation. Then answer the following.

1. What is the probability that both cards are odd?

2. What is the probability that exactly one card is odd?

These are the two questions I am having trouble with...Thank a lot!
