(1) In 3D space, let the vertices of a cube be the eight points with coordinates either zero or one. How many distinct distances between such points are possible? Find them.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

a

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 %
