# Demand Using the probability density function in Exercise 38, determine the number of tons that should be ordered each week so that the demand can be met for 90% of the weeks. Demand The weekly demand x (in tons) for a certain product is described by the probability density function f ( x ) = 1 36 x e − x / 6 , [ 0 , ∞ ] Find and interpret each probability. ( a ) P ( x &lt; 6 ) ( b ) P ( 6 &lt; x &lt; 12 ) ( c ) P ( 12 ≤ x ≤ 24 ) ( d ) P ( x &gt; 12 ) = 1 - P ( x ≤ 12 ) BuyFind
