Refer to the spinner. Find the odds of the spinner not landing on an even number. • 1:3
•1:1
•2:1
•1:2

Explanation:

We have three numbers that aren't even, and they are {1,3,5}

There are three numbers that are even, and they are {2,4,6}

The odds in favor of not getting an even number is 3:3 = 1:1

To list the odds in favor, you write the number of ways to get what you want, followed by a colon, then the number of ways to get what you don't want. In this case, both counts are 3. The ratio 3:3 reduces to 1:1 after dividing both parts by 3.

1:1

Step-by-step explanation:

how many odd sections are even: 3

how many sections are not even: 3

the odds are 3 : 3= 1:1

odds are what you expect to come out versus what you don't expect(favorable to un favorable).

confusion comes in when talking about probability

probability is what you want to come out versus the total chances whether odd or even(favorable to total outcomes). eg

in this example

the probability of it not landing on the even number is:

number of odd sections=         3     =   1:2

number of total outcomes=     6

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
