17.6 Probability. I toss a coin 1000 times and observe the outcome “heads” 519 times. Which of the following can be concluded from this result?
(a) This is suspicious because we should observe 500 heads if the coin is tossed as many as 1000 times.
(b) The probability of heads is approximately 519.
(c) The probability of heads is approximately 0.519.
(d) Nothing can be concluded until we verify that the pattern of heads and tails exhibits a reasonably regular pattern.
