There are y black socks and 5 white socks in a drawer. Joshua takes at random two socks from the drawer. The probability that Joshua takes one white sock and one black sock is (a) Show that 3y2 – 28y + 60 = 0

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 %
