Consider x = The weight of student in AURAK
a) Probability of student weight is more than 90
P[x>90]
=P[Z>1.43]
=1-0.9236...........................by using normal probability table.
=0.0764
b) The probability of student weight is between 73 and 87
=P[-1<z<1]
=0.8413-0.1587.....................by using normal probability table.
=0.6826
