Toss a fair coin five times and record the results. Use T to denote tails facing up and H to denote heads facing up.

(a) [5 points] How many different results can we get?

(b) [10 points] What is the probability that there is only one T in the result? Round answer to 4 decimal .

(c) [10 points] What is the probability that at least two T's in the result? Round answer to 4 decimal .

Let H (Heads) and T (Tails) denote the two outcomes of a random experiment of tossing a fair coin. Suppose I toss the coin infinite many times and divide the outcomes (which are infinite sequences of Heads and Tails) into two types of events: (a) the portion of H or T of is exactly one half (e.g.HTHTHTHT... or HHTTHHTT...) (b) the portion of H or T is not one half (i.e. the complement of event (a). e.g. HTTHTTHTT...). What are...

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...
