Explanation Given information: f ( x ) = 1 18 x , 0 ≤ x ≤ 6 and Pr ( 1 ≤ X ≤ 2 ) Formula used: 1) Power rule of integration : ∫ x n d x = x n + 1 n + 1 , n ≠ − 1 2) Area under the graph of f ( x ) is given by a definite integral P ( a ≤ X ≤ b ) = ∫ a b f ( x ) d x Calculation: The probability that X lies between the endpoints of the given interval [ a , b ] is given by the area under the graph of a function f ( x ) from a to b So, area under the graph of f ( x ) is given by a definite integral P ( a ≤ X ≤ b ) = ∫ a b f ( x ) d x Thus, Pr ( 1 ≤ X ≤ 2 ) = ∫ 1 2 f ( x ) d x = ∫ 1 2 1 18 x d x

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a…
