What is the theoretical probability of rolling an odd number on a 6-sided die?

• 1/6
• 1/3
• 3/6 or 1/2
• 0/6

In theoretical probability if I rolled a 6-sided die 12 times, how many 1's should you expect to roll?

• 1
• 2
• 3
• 4
• 6

In theoretical probability if I flipped a coin 20 times, how many heads should I expect to get?

I flipped a coin 20 times. There were 13 heads and 7 tails. Which best explains why the experimental probability differs from the theoretical probability?

• There is something wrong with the coin because it should be 10 heads and 10 tails.
• Theoretical probability is just a guess and the real probability of flipping heads should be 65% and the real probability of flipping tails should be 35%
• If I were to continue flipping the coin to make a larger sample (50, 100, 1000 flips), the experimental probability should start to look more like the theoretical probability.

You have a mini bag of skittles that contains 10 red, 5 yellow, 5 green, 6 orange, and 8 purple. To calculate the probability of getting a purple skittle, what would be your denominator?
