Question

a friend flips a coin 50 times and says that the probability of getting a head is 60% because he got thirty heads. is the friend referring to an estimated probability or the probabilitys true value? explain.
choose the correct answer below.
a. this is the probabilitys true value because it is based on an experiment.
b. this is the probabilitys true value because it is not based on an experiment.
c. this is an estimated probability because it is based on the relative frequency at which an event happens after infinitely many repetitions.
d. this is an estimated probability because it is based on an experiment.

Explanation:

The friend flipped a coin 50 times and got 30 heads. True probability of getting a head in a fair - coin flip is 0.5. The 60% probability he calculated is based on a finite - number of trials (an experiment), which is an estimated probability calculated from relative frequency in the experiment.

Answer:

D. This is an estimated probability because it is based on an experiment.
