see the photo for details

The capacity of the stake supporting an electrical transmission tower  is lognormal random variable with  an average capacity of 1X0 tons and a variation coefficient  of 3X  (please type the last number of your student number instead of X). For example, if the last number of your student number is 4, the values will be 140 tons and 34%, respectively).

  1. What are the chances that the stake will remain intact under a load of 1X0 tons? (Instead of X, type the last number of your student number. For example, if the last number of your student number is 4, the value will be 140 tons)
  2. A pile loading test that is inserted during the placement of the stake indicates that the stake can support at least 85+X tons of load. What are the chances that the stake will remain intact under a load of 1X0  tons in such a situation? (Instead of X, type the last number of your student number. For example, if the last number of your student numara is 4, the values will be 89 tons and 140 tons, respectively).

Question 5) The capacity of the stake supporting an electrical transmission tower is
lognormal random variable with an average capacity of 1X0 tons and a variation coefficient
of 3X (please type the last number of your student number instead of X). For example, if the
last number of your student number is 4, the values will be 140 tons and 34%, respectively).
a) What are the chances that the stake will remain intact under a load of 1X0 tons?
(Instead of X, type the last number of your student number. For example, if the
last number of your student number is 4, the value will be 140 tons)
b) A pile loading test that is inserted during the placement of the stake indicates that the
stake can support at least 85+X tons of load. What are the chances that the stake
will remain intact under a load of 1X0 tons in such a situation? (Instead of X, type
the last number of your student number. For example, if the last number of your
student numara is 4, the values will be 89 tons and 140 tons, respectively)..
