    It is equal to the theoretical probability. It is 8% lower than the theoretical probability. It is 8% higher than the theoretical probability. The experimental probability cannot be concluded from the data in the table.

    1/2*63/150?

    What is the theoretical probability of getting heads in this case of 150 tosses?

    No that is what happened in the experiment. In theory, if you toss a coin 150 times, how many heads do you expect?

    Each time you toss a coin, there is an equal probability of getting heads or tails. If you toss a coin 150 times, there is a theoretical probability of getting heads 75 times and tails 75 times. Do you understand my question now?

    A coin is flipped 150 times Heads Tails Experimental outcome: 63 87 Theoretical outcome 75 75 Ok?

    Now let's look at percentages. The theoretical 75 heads are: 75/150 * 100 = 50% The actual heads are: 63/150 * 100 = 42% The actual tails are: 87/150 * 100 = 58%

    A coin is flipped 150 times Heads Tails Experimental outcome: 63 (42%) 87 (58%) Theoretical outcome 75 (50%) 75 (50%) Now look above at the "Heads" column. The theoretical heads result is 50%. The experimental (actual) heads result was 42%. Now read your choices and choose the correct answer.

    Exactly, since 42% is 8% less than 50%. Good job!
