Question

Which best describes the complement of spinning any number less than 3?

Answer 1

Answer:

b)  Complement of spinning any number less than 3 is Spinning 3 or 4.

Step-by-step explanation:

COMPLIMENT of any Set A  is the set of all the elements which are in the  sample space but NOT IN SET A.

Here, Event E  = Spinning a spinner with 4 parts and getting a number less than 3.

Here, Sample Space = {1,2,3,4}

Also, as outcomes is LESS THAN 3, ⇒   E  = {1 ,2}  

Now, Compliment E  = Sample Space - { Elements in set E}

                                    = {1,2,3,4} -  {1 ,2}

or, E'  = { 3,4}

Hence,  complement of spinning any number less than 3 is Spinning 3 or 4.

Answer 2

Answer:

Spinning a 3 or 4

Step-by-step explanation:

The numbers that are less than 3 on the spinner, are 1 and 2. Therefore, the complement or opposite of that are all the numbers other than 1 and 2. So the answer is 3 and 4.
