This is an example of experimental probability that was observed over a period of 38years.
94 tornadoes occurred in the 38year period.
This means averagely,
[tex]\begin{gathered} \frac{94}{38}\text{ tornadoes occurred yearly} \\ 2.474\text{ tornadoes per year} \end{gathered}[/tex](a) The probability that there will be 2 tornadoes in the next year will be;
[tex]\frac{no\text{ of expected tornadoes}}{no\text{ of total tornadoes}}=\frac{2}{2.474}=0.808\text{ (to 3 decimal places)}[/tex]Therefore, the probability that there will be 2 tornadoes in the next year = 0.808
(b) The probability that there are 3 or more tornadoes in the next year is 0. This is because based on the experimental probability sampled over a 38year period gave 2.474 tornadoes per year. Hence, expecting more tornadoes than this average is highly unlikely.
