Beyond the Answer
To calculate the probabilities for parts (a) and (b), we can use the information given that the probability of being hit by a major tornado in any single year is \( \frac{1}{5} \). For part (a): The probability that the state will be hit by a major tornado two years in a row is calculated as follows: \[ P(\text{2 years}) = P(\text{hit in year 1}) \times P(\text{hit in year 2}) = \frac{1}{5} \times \frac{1}{5} = \frac{1}{25} = 0.04000 \] Now for part (b): The probability that the state will be hit by a major tornado in three consecutive years is calculated in a similar way: \[ P(\text{3 years}) = P(\text{hit in year 1}) \times P(\text{hit in year 2}) \times P(\text{hit in year 3}) = \frac{1}{5} \times \frac{1}{5} \times \frac{1}{5} = \frac{1}{125} = 0.00800 \] So, the answer for part (b) is: 0.00800 (Simplifying this shows it is \( \frac{1}{125} \), which rounds to five decimal places as needed).
