Answer 1

Answer:

8/9 is the probability of not spinning a 3.

Step-by-step explanation:

A spinner has equal 9 sections which are numbered from 1 to 9.The probability of spinning any number is 1/9.

So probability of spinning 3 will be 1/9.

Now the probability of not spinning a 3 will be = 1 - probability of spinning 3.

= 1 - 1/9 = 8/9.

Therefore answer is 8/9.  

Answer 2

The probability of not spinning a 3 is 8/9

The probability of spinning a 3 is given as:

p(3) = 1/9

The probability of not spinning a 3 is calculated using the following complement rule:

P(Not 3) = 1 - P(3)

So, we have:

P(Not 3) = 1 - 1/9

Evaluate the difference

P(Not 3) = 8/9

Hence, the probability of not spinning a 3 is 8/9
