Example: You toss a coin three times and it comes up "Heads" each time ... what is the chance that the next toss will also be a "Head"? The chance is simply 1/2, or 50%, just like ANY OTHER toss of the coin. What it did in the past will not affect the current toss!
What is the probability of getting at least one head? We toss a fair coin three times. What is the probability of getting at most one head? If you flip a fair coin 7 times, what is the probability that you will get exactly 2 tails? If you flip a fair coin 5 times,...
If we apply this to the coin toss, there is one desired outcome (for example, heads) out of two possible outcomes. Thus, the probability of a coin toss coming out heads is 1/2. We can also use probability to determine the likelihood that two events will happen together. If you roll ...
A coin is tossed 2 times. The toss resulted in one head and one tail. What is the probability that the first throw resulted in a tail? Solution: The sample space of a coin tossed two times is given as S = {HH, HT, TH, TT} ...
