spinning a 3?
enter your answer as a fraction, in simplest form, in the box.

show your answer

Step-by-step explanation:

Numbers 1 thru 9... probability of spinning a 3 is 1/9 and the probability of not spinning a 3 is 8/9

1/9, 8/9

Step-by-step explanation:

probability of a desired outcome =

= (number of desired outcomes)/(total number of outcomes)

The total number of outcomes is 9.

(a) The probability of spinning a 3

There is only 1 desired outcome, a 3.

p(3) = 1/9

(b) What is the probability of not  spinning a 3?

The probability of spinning a 1, 2, 4, 5, 6, 7, 8, or 9.

There are 8 desired outcomes.

p(not 3) = 8/9
