You perform a collapse analysis for a bridge structure, and you obtain a median collapse

capacity of $0\mathrm{.}5$g and a mean collapse capacity of $0\mathrm{.}7$g$.$ Assuming the collapse capacity follows a lognormal

distribution, what is the probability of collapse at an intensity of $0\mathrm{.}2$g i$.$e$.,$ the probability that the collapse

capacity is less than $0\mathrm{.}2$g$?$
