4) A civil engineering student delivered a cylinder of concrete for the "concrete strength competition" held between universities. The strength of the student's concrete cylinder is normally distributed with N(410, 91) KN The student will compete in the last place in the competition and the two highest strengths in the competition so far are 500 kN and 350 kN. a) What is the probability that the student will be second in the competition? b) Whether the student's cylinder was tested under a load of 450 kN, the cylinder showed no signs of breaking. What is the probability that the student will be first?
