A train can either be early, on time or late.
The probability that the train is early is 0.2
The probability that the train is on time is 0.5

Work out the probability that the train is late.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

um is there supposed to be a picture?
