1.	A fair coin is tossed 15 times. Determine the probability in which no heads turned up.(a) 2.549 * 10^-3(b) 0.976(c) 3.051 * 10^-5(d) 5.471I have been asked this question by my college professor while I was bunking the class.This interesting question is from Counting in division Counting of Discrete Mathematics
Answer» The correct answer is (c) 3.051 * 10^-5 Easiest explanation: ACCORDING to the NULL hypothesis it is a FAIR coin and so in that case the probability of FLIPPING at least 59% tails is = ^15C0(0.5)^15 = 3.051 * 10^-5.
