The period T of a simple pendulum is given by T=2πLg−−√ where L is the length of the pendulum and g is the acceleration due to gravity. Assume that g = 9.80 m/s2 exactly, and that L, in meters, is lognormal with parameters μL = 0.6 and σ2L=0.05. Supposed 10 pendulums are constructed. Find the probability that 4 or more have periods greater than 3 seconds. Probability =
