Function f gives the temperature, in degree Celsius, t hours after midnight. Use function notation to write an equation or expression for each statement:a. The temp at 12 p. m.b. The temp was the same at 9 a. m. and 4 p. m.c. It was warmer at 9 a. m. than 6 a. m.

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 %
