A coin was flipped twenty times and landed heads fifteen times. Based upon this information, answer the following the question:
If the coin is balanced (fair) what is the probability of a head on the toss?
If the coin is not balanced (not fair), what is the probability of a head on the next toss?
If a fair coin is flipped three times what is the probability of getting the following outcomes?
- Zero Heads
- One or more heads
= One head followed by two tails.
For a fair coin, probability of a head on a toss, p = 1/2 == 0.5
If the coin is not a fair coin, the probability of head in a toss, p = 15/20 == ...
