Five coins all balanced the same were tossed 150 times. Note that, while the coins are all balanced the same, they may or may not be fair coins. Since five coins were tossed, the possible number of heads for each toss could be zero through five. The following table gives the number of tosses that yielded each of these six outcomes.

Given these results, which of the following probabilities is most likely to be the chance of each coin flipping to a head?

a)0.20

b)0.35

c)0.50

d) 0.65

e) 0.80
