A coin was flipped 150 times. The results of the experiment are shown in the following table:

Heads Tails
90 60

Which of the following best describes the experimental probability of getting heads?
It is 10% higher than the theoretical probability.
It is 10% lower than the theoretical probability.
It is equal to the theoretical probability for this data.
The experimental probability cannot be concluded from the data in the table.

its A

Wouldn't theoretical be 75?

anonymous · Answer

Yep it's A because the theoretical probably is 50-50. Therefore the number of heads and tails should be the same. But since there were more heads then tails it indeed is A

Okay thank you for clarifying. I think I'm just over thinking it :D

yeah yeah, just keep it simple :)
