Question

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.

Answer 1

I'm so confused

Answer 2

Okay so you said it would be 50/50 right? The coin was flipped 150 times-

150/2=75

90 is more than 10% higher than 75....

Answer 3

hmmmm I think this is a mistake

Answer 4

I'm just trying to understand. The other girl that came on my old question just shot the answer out- I really just need help.

Answer 5

Is this problem from the textbook or did the teacher write it or something

Answer 6

actually the 10% is just a rough estimate, so it's not the exact answer.

Answer 7

I was leaning more towards D because either way, 10% higher & 10% lower aren't even close to 90.

Answer 8

actually it is pretty close to 90.

10% of 75 is 7.5 so
75+7.5=82.5

Answer 9

@ganeshie8 Can you have a look at this for me, please?! Thanks

Answer 10

The experimental chance is 90/150 which is 60% right, and then the theoretical of probability is half the chance or 50% so what can we conclude?

Answer 11

The theoretical is 50% because you can either get a heads or tails, so it gives us a 50/50 chance, I hope this makes sense

Answer 12

Thank you everyone
