Heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. find the regression equation, letting the first variable be the independent (x) variable, and predict the weight of a supermodel who is 171 cm tall.
height 176,168,178,174,176,176,178
weight 56,50,58,55,54,55,57

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 %
