(b) What is the probability of obtaining xequals240 or more individuals with the characteristic? P(xgreater than or equals240)equals nothing (Round to four decimal places as needed.) (c) What is the probability of obtaining xequals180 or fewer individuals with the characteristic? P(xless than or equals180)equals nothing (Round to four decimal places as needed.)

answer:

hi

Step-by-step explanation:

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 %
