5)The capacity of the pile supporting an electrical transmission tower is a lognormal random variable with an average of 110 tons and a coefficient of variation of 31% a) What is the probability that the pile will remain intact under a load of 110 tons? b) A pile loading test performed during the installation of the pile shows that the pile can support a load of at least 85+1 tons. In such a case, what is the probability that the pile will remain intact under a load of 110 tons? Hint: The possible outcomes for this question are within the values given below 0.4417 0.4398 0.4380 0.4361 0.4343 0.4325 0.4307 0.4289 0.4272 0.4254 0.6713 0.5898 0.5414 0.5108 0.4903 0.4760 0.4655 0.4575 0.4512 0.4460
