Question

Suppose that in Exercise 1.6 you decide to flip the coin 100 times. a. What conclusion would you be likely to draw if you observed 95 heads? b. What conclusion would you be likely to draw if you observed 55 heads? c. Do you believe that, if you flip a perfectly fair coin 100 times, you will always observe exactly 50 heads? If you answered "no, " then what numbers do you think are possible? If you answered "yes, " how many heads would you observe if you flipped the coin twice? Try flipping a coin twice and repeating this experiment 10 times and report the results.

Explanation / Answer

a) If after flipping a coin 100 times we obtain 95 heads, we say that the coin is not an unbiased one as the number of heads is much more than number of tails obtained.

b) If after flipping a coin 100 times we obtain 55 heads, we say that the coin is an unbiased one as the number of heads are almost equal to the number of tails obtained.

c) On flipping a coin 100 times we would expect 50 heads and 50 tails but there is no surity that the observed numbers would be these.

On flipping a coin twice ,10 times I got 11 heads and 9 tails.
