Answer:
The relative frequency of the coin landing heads up is 0.4 or 40%.
Explanation:
We are given that,
Total number of times coin is tossed = 600
Number of times heads comes = 240
Since, 'relative frequency' is the fraction of number of times an event occurs and the total number of events.
Thus, the relative frequency that heads comes =

i.e. Relative frequency that heads comes = 0.4 or 40%
Thus, the relative frequency of the coin landing heads up is 0.4 or 40%.
