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.

    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....

    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.

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

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

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

    actually it is pretty close to 90. 10% of 75 is 7.5 so 75+7.5=82.5

    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?

    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
