see the photo for details A civil engineering student has delivered a cylinder of concrete for the "concrete strength competition" held between universities. The strength of the student's concrete cylinder is normally dispersed with N(4X0, 9X) kN (write the last number of your student number instead of X). For example, if the last number of your student number is 4, the normal distribution will be N(440.94). The student will compete in the last place in the competition and until that point the two highest strengths in the competition are 500 kN and 350 kN. What are the odds of the student coming second in the competition? The student's cylinder is being tested and under a load of 450 kN the cylinder has shown no signs of breaking. What are the chances of the student winning first place?
