On a 6-sided die, which is more likely?

• Rolling an odd number
• Rolling an even number
• They are both equally likely.

Experimental Probability is:

• What Will happen 
• What actually happens
• What should happen
• What I think Happens

Without looking, Tammy takes a marble out of a bag that contains 10 red marbles, 15 green marbles, and 25 blue marbles. She records its color and returns the marble to the bag. If Tammy repeats this process 90 times, how many times can she expect to pull out a red marble?
