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.

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

63

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.

b?

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