Answer:
Find the relative frequency for the event "heads" for each friend:
Friend 1: 0.59 (41/70)
Friend 2: 0.7 (49/70)
Friend 3: 0.37 (26/70)
If the friends combine their results to get 116 heads and 94 tails, what is the relative frequency for the event "heads"?
0.55 (116/210)
Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
For Friend 1, basing it off the 0.59 frequency from earlier, I would expect the heads to be around 413.
Friend 2, 490
Friend 3, 259
