(a) Use the central limit theorem to determine the probability that if you toss a coin 50 times, you get fewer than 20 heads.

(b) A coin is continuously tossed until the heads come up 20th time. Use the central limit theorem to estimate the probability that more than 50 coin tosses are required to get the 20th head.

(c) Compare your answers from parts (a) and (b). Why are they close but not exactly equal?

Suppose you toss a coin 100 times. Should you expect to get exactly 50 heads? Why or why not? A. Yes, because the number of tosses is even, so if the coin is fair, half of the results should be heads. B. No, because the chance of heads or tails is the same, the chance of any number of heads is the same. C. No, there will be small deviations by chance, but if the coin is fair, the result...
