Relative Frequency

1 / 25

A coin is tossed $50$ times and heads appear $28$ times. The relative frequency of heads is:

2 / 25

Which statement best describes relative frequency?

3 / 25

A die is rolled $120$ times and the number $4$ appears $18$ times. What is the experimental probability of getting $4$?

4 / 25

As the number of trials increases, the relative frequency tends to:

5 / 25

In an experiment, the relative frequency of an event is $0.8$ after many trials. This suggests:

6 / 25

If an event never occurs in $100$ trials, its relative frequency is:

7 / 25

A spinner is spun $200$ times and lands on red $50$ times. What is the relative frequency of red?

8 / 25

Which of the following is an example of experimental probability?

9 / 25

A student records rainfall on $12$ days and finds rain on $3$ days. The relative frequency of rain is:

10 / 25

Which factor improves the accuracy of relative frequency as an estimate?

11 / 25

A coin is tossed repeatedly. After many trials, the relative frequency of heads is $0.49$. This indicates:

12 / 25

If relative frequency $= 1$, then the event is:

13 / 25

A bag is tested experimentally and red ball appears $45$ times in $90$ draws. Estimated probability of red ball is:

14 / 25

Which of the following best explains why relative frequency may differ from theoretical probability?

15 / 25

If relative frequency of success increases with trials, it means:

16 / 25

A coin is tossed $10$ times and heads appears $7$ times. The relative frequency is:

17 / 25

Which situation best demonstrates relative frequency?

18 / 25

In $500$ trials, event $A$ occurs $125$ times. Relative frequency of $A$ is:

19 / 25

If an event has relative frequency close to $0$, it is:

20 / 25

Which of the following values is NOT possible for relative frequency?

21 / 25

Relative frequency is mainly used to:

22 / 25

A spinner experiment gives relative frequency $0.33$ for blue. This implies:

23 / 25

When trials increase from $100$ to $1000$, relative frequency:

24 / 25

Relative frequency depends on:

25 / 25

If event occurs $60$ times in $200$ trials, its relative frequency is:
