### solving # 4

Question of problem 4.

1. If you flip a coin 150 times, about how many times would you expect to get heads?

If you divide 150 into 2 gives you 75/150

2. The letters a, e, i, o, u, and y are vowels. If one letter of the alphabet is chosen at random, what is the probability it is a vowel?

The answer would be 7/26, how, add all the vowels together and, how many the probability is 7/26

3. If you randomly pick a date in April, how many equally likely outcomes are there?

The answer would be 30, because there are 30 days in April.

4. A magician asks you to pick a card, any card, from a standard deck of 52 cards. What is the probability of picking an ace?

The probability of picking a ace would be 4/52 and you can simplify to 2/26and you can do it one more time to be 1/13. So the answer would be 1/13

This is my question if you have 10 pens, 14 pencils, 16 erasers, and 9 rulers. How many outcomes can you have?
