Fundamental Concept

This exercise can be answered by conducting a coin toss and recording the results of each toss.

I conducted this experiment and the results of my test are as follows:

Heads - 5 times

Tails - 10 times

Answering the Exercise

Considering the results of the coin toss experiment, the table should be completed as follows:

Heads

Tally - the tally for heads is 5 written in tally marks

Frequency - the frequency is 5

Tails

Tally - the tally for tails is 10 written in tally marks

Frequency - the frequency is 10

Out of 20 times, how many times did the tail show up?

The tail showed up 10 out of 20 times. The probability of getting a tail is 1/2.

Out of 20 times, how many times did the head show up?

The head showed up 5 out of 20 times. The probability of getting a tail is 1/4.
