A fair die is to be rolled 20 times. Find he expected value of the number of times (a). 6 appears.
(b). 5 or 6 appears.
(c). An even number appears. (d). Anything else but 6 appears.
please explain the step

A fair 6-sided die is rolled and you note whether the number facing up is even or odd. If an even number is rolled then a fair coin is flipped three more times and the number of heads is noted. But if an odd number is rolled then the coin is flipped only twice more and the number of tails is noted. How many possible outcomes are there for this experiment? (a) 43 (b) 20 (c) 7 (d) 45 (e)...
