Subpart A,B,C

The daily temperature in Lakewood during the month of December is normally distributed with a mean of 46°F and a
standard deviation of 4°F.
a. On the following diagram, shade the region
representing the probability that a random day in Lakewood
is greater than 40°F.
b. Calculate the probability that the temperature on a
randomly chosen day in December is greater than 40°F.
c. Calculate the expected number of days in December
that the temperature will be greater than 40°F.
d. On a randomly selected day in December, the
probability that the temperature is above k°C is 0.25. Find
the value of k.
e. Find the probability that exactly twenty-nine days in
December will be greater than 40°C.
f. Find the probability that at most twenty-nine days in
December will be less than 40°C.
