The odds of spinning red on a spinner are 2: 7. what is the probability of not spinning red?

5:7.

To figure this, you just need to read it like the probability of getting a red is 2/7, and therefore any other color on the spinner must be NOT red. You consider the complement, which here would be:

1 - P(landing on red) = 1 - 2/7 = 5/7

In general, the complement of a single event is 1 minus the probability of that event occuring.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
