Mark, Carrie, Max, and Jane are doing a probability experiment in math class. They flip a coin 200 times and record their results.

Heads:120
Tails:80

Question 2 on their lab sheet asks for the theoretical probability of flipping heads. They come up with four different answers:

Mark:1/2 Carrie:3/5 Max:2/5 Jane:2/3

Who has the correct theoretical probability?

Max

Jane

Mark

Carrie <<I choose this one

If it is an unbiased coin, Max.
It would be Mark because a coin has two sides, 50/50 chance for a head or a tail.
I agree Mark, I read the wrong name. Thanks, Luke
