what could happen if a fair coin is flipped four times. The sample space for x = number of heads in four flips of a coin . Unit 20: Random Variables | Student Guide | Page 8. Now, we . Page 16 . mean 70 mm and standard deviation 3 mm.
But can anybody explain? If you flip a coin 16 times, what is the probability that you will get 8 heads and 8 tails? Is this even GMAT doable? Missing: mm.
(Flipping four coins.) ' %_. (a) Here are all the possible outcomes, 16 in total: TTTT TTHH THHH So the probability of getting exactly 8 heads is = Problem 2.6. . least probable macrostate is qA = 0, qB = 100, with probability 4.53 x 1058 / 1.68 X 1096 = 2.7 x (tinyi). mm) _ _.
