###### Question details

A cement truck delivers mixed cement to a large construction
site. Let *x* represent the cycle time in minutes for the
truck to leave the construction site, go back to the cement plant,
fill up, and return to the construction site with another load of
cement. From past experiences, it is known that the mean cycle time
is *μ* = 46 minutes with *σ* = 9 minutes. The
*x* distribution is approximately normal. What is the
probability that the cycle time will *exceed* 61 minutes,
given that it has exceeded 44 minutes?

a. 0.081

b. 0.588

c. 0.048

d. 0.588
