The weighs of a large shipment of coconuts are normally distributed with a standard deviation of 0.71kg. The probability that a coconut weighs less than 2.1kg is 10.2%. To the nearest hundredth of a kilogram, what is the mean weight of a coconut in this shipment?

(a) (8%) compute the probability of an even integer among the 100 integers 1! , 2! , 3! , until 100! (here n! is n factorial or n*(n-1)*(n-2) *… 1) (b) (16%) compute the probability of an even integer among the 100 integers: 1, 1+2, 1+2+3, 1+2+3+4, …., 1+2+3+… + 99, and 1+2+3+… + 100

Can someone pls ! pls answer all. no explanation needed..
