Question

Mason is plays a game flipping two fair coins. He wins if both coins land heads up. If Mason plays 200 times, how many times should he expect to win. ​

Answer 1

Mason should win about 50 games

Explanation:

There are four possibilities when flipping two coins:

1st coin could be heads (H) or tails (T)

and

2nd coin could be heads (H) or tails (T)

multiply these together and you get 4

the sample space would look like this:

H and H

H and T

T and H

T and T

Mason only wins when there is a head followed by a head. This is 1 out of the four outcomes. His chances of winning is 1 in 4, or 25%. If mason plays 200 times, you should expect him to win about 25% of the time. 25% of 200 is 50. Mason should win about 50 games.
