Probabilities as frequencies

• First, let’s clarify the concept of uncertainty.
• In Math we define uncertainty in terms of probability.
• For example, if we toss a coin then we can expect a particular outcome, drawing tails, will occur with a probability of 10%. Then we expect that among many repeated trials that outcome will be seen in approximately one out of ten cases.
• Uncertainty must be seen with repeated events, not a single one.
