An engineer is proof-reading his report and finds that he has mistakenly used micrometers as a unit of measure. His experiment showed a measurement of 2
micrometers, but the government requires the measurement to be in millimeters.
How should the engineer record the measurement (if there are 1000
micrometers in 1 millimeter)?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

the real question is why is this guys last name heavyfoot
