I need help on this pls

a) B

b) C

Step-by-step explanation:

With 8 equal sections, there is 1/8 chance to land on each section.

There are 2 1's, so the chance to land on a one is 2/8 represented by B.

There are 4 2's, so the chance to land on a two is 4/8 represented by C.

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 %

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
