The relative frequency of the coin landing on tails is 60% when a coin is flipped 70 times and lands on tails 42 times. option D is correct.
Relative frequency for a repeated event:
- Relative frequency is an estimate of the probability that is calculated from repeated trials of an event.
- It is given by the ratio of the number of times an event occurs to the total number of events occurring.
- Relative frequency = f/n
- f-number of times an occurs and n-total number of events
Calculating the relative frequency:
Given that,
A coin is tossed 70 times and lands on tails 42 times.
So, f=70 and n=42
Thus, the relative frequency = [tex]\frac{42}{70}[/tex] = 0.6
Therefore, relative frequency 60% of the coin lands on tails If a coin is tossed 70 times and lands on tails 42 times.
