Problem 10) A fair coin is tossed 20 times. A fair coin means that the probability of getting a head is the same as the probability of getting a tril. Let X be the number of coins of getting head. Note that there are only two possible outcomes: getting head or tail after tossing the coin X follows a binomial distribution with n =20, p=0.5. Answer the following questions (Question) Find PX-17).
(a) A fair coin is tossed 6 times. What is the probability that it will land on heads exactly 3 times?
(1 point) A fair coin is tossed 12 times. What is the probability that: a) Exactly 10 heads appear?0.01611328125 b) At least two heads appear? 0.98095703125 c) At most 9 heads appear? 0.92724609375
A fair coin is tossed 100 times. Determine the probability that the number of heads observed is at least 42 and at most 49 (inclusive). Approximate your answer using the normal approximation.
