To find the probability that a continuous random variable falls in a specified range, we need to calculate the area under the probability density function for that range. The cumulative probability function gives us the probability that the random variable is less than or equal to a specific value. The difference between the cumulative probabilities at the lower and upper end of the range will give us the probability that the random variable falls in that range. Therefore, the correct answer is A - range.
