Question7
Since we are tossing a coin 8 times and each toss has only two possible outcomes.
Then the total number of outcomes is simply 2^8 = 256
Question8
If 3 coins flipped the possible outcomes are
And we can see only two outcomes are possible for matching all 3 coins (HHH) and (TTT).
Probability = 2/8 = 1/4

The next four questions (5 to 8) refer to the following: An unfair coin is tossed three times. For each toss, the probability that the coin comes up heads is 0.6 and the probability that the coin comes up tails is 0.4. If we let X be the number of coin tosses that come up heads, observe that the possible values of Xare 0, 1, 2, and 3. Find the probability distribution of X. Hint: the problem can be solved...
