  • Expected frequency is the frequency we expect to see based on the theoretical probability of an outcome in a probability experiment.
  • The expected frequency is calculated by multiplying the number of trials by the theoretical probability.
  • The expected frequency formula is: expected frequency = number of trials * theoretical probability.
  • The expected frequency is an estimate and may not be the exact outcome in the experiment.
  • The formula for calculating the theoretical probability is: probability = number of successful outcomes / total number of outcomes.
  • The expected number of days that SAR will get stuck in traffic over 20 work days is 3.
  • The expected number of times Luca would draw a 7 or an 8 after repeating the process 40 times is 6.
