Suppose that blood chloride concentration (mmol/l) has a normal

Suppose that blood chloride concentration (mmol/L) has a normal distributionwith mean= 104 and standard deviation= 5 (information in the articleMathematical Model of Chloride Concentration in Human Blood, J. of Med.Engr. and Tech., 2006: 2530).

i. What is the probability that chloride concentration equals 105? Is at most105? 

ii. What is the probability that chloride concentration diers from the meanby more than 1 standard deviation? Does this probability depend on thevalues of mean and standard deviation ? 

iii. How would you characterize the most extreme 0.1% of chloride concentration values?
