Answer 1

Date The graph to the right is the uniform Probability density function for a friend who is x minutes Density o 20 late Time (min) 20 and a) The probability that the friend is between 130 minutes late is X Nuco, 30) a < x < b b-a لان < x < 30 30 There is a 10% prob. the friend will arrive within fra = f(0) = IP (20 < x < 30 30 20).fle) V3 |p(20 < x 30) 0.3383 buy is 10 A.N. There is a 10 % probability the friend Iloill amive within how many minutes.? - 0.10 30X0.10 x = 3 o 30 - 30 13 minutes.
