What can you say about 4a) ? If the probability is 1, what % of the time will something happen? If it's 0, what % of the time will something happen?

On c), what is the probability of heads or tails when you toss a coin? If you're not sure, try it. Toss the coin 100 times -- what percentage of the time is it tails?
