Question

Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip the coin 200 times and calculate the relative frequency of heads and tails.
Outcome Heads Tails
Relative frequency 0.38 0.62


Select from the drop-down menus to correctly complete each statement.

The relative frequency of heads is

40%.

Mr. Clark's claim about the theoretical probability is likely to be

.

This means that the theoretical probability of tails is most likely
for this coin.

Answer 1

While I'm not sure what the answer choices were, his claim is likely to be true. 
Since he claims the probability of heads is 40%, that should be what we see in an experiment.  0.38 is very close to 0.40, or 40%, so this is true.  Therefore his claim is likely to be true, and the probability of tails should be about 60%.
