WebIn the second example, the frequency distribution shows the number of American voters in the millions according to age. To find the probability for a voter chosen at random in the age range 18 to 20 years old, the frequency of 4.2 million is divided by the total of 260.8 million. This gives a probability of 4.2/260.8 = 0.016. WebOther Types of Probability. Subjective Probability is your belief that a particular event will occur. There’s no science behind this.
