Explanation Given: The given condition is: An insurance company expects that 30% of high risk drivers will be involved in an accident during the first 50 days of a calendar year. Options are: a. 0.15 b. 0.34 c. 0.43 d. 0.57 e. 0.66 Approach: If X is a random variable with probability density function, f ( x ) = a e − a x for x in [ 0 , ∞ ] , Then, μ = 1 a and σ = 1 a . Calculation: Consider the given condition: An insurance company expects that 30% of high risk drivers will be involved in an accident during the first 50 days of a calendar year. The probability of accident in first 50 days is, P ( 0 < X < 50 ) = 0.3 . So, ∫ 0 50 a e − a x d x = 0
