Question

Points M and N are both on ZB with M between Z and N. ZM = 10
, NB 2, and ZB = 20. If a point on ZB is chosen at random, what is the
probability that the point is on MN?

Answer 1

Answer:

Your answer is 40%

Step-by-step explanation:

It is 20 units between Z and B.

We add 2 more points, and one of them is at the the halfway point of the entire line.(M)

One of them is only 2 units away from B.(N)

That means our line is halved, so from 20/20 possible places a point could go and land in the right area is now 10/20.

Minus 2 from that; to take into count of the N to B, and you have 8/20

8/20 is just 40%
