Question

Emily is playing a board game that has a spinner divided into equal sections numbered 1 to 18. The probability of the spinner landing on an even number or a multiple of 3 is ___. The probability of the spinner landing on an odd number or a number between 4 and 15 (both numbers excluded) is ___
The probability of the spinner landing on an even number or a multiple of 3 is ___?
1/6
1/3
1/2
2/3
5/6

The probability of the spinner landing on an even number or a multiple of 3 is ___?

13/18
1/3
7/9
2/3
5/6

Answer 1

Answer:The probability of the spinner landing on an even number or a multiple of 3 is 1/6.

Step-by-step explanation:

$Probability=\frac{\text{number of outcomes}}{\text{total number of outcomes}}$

Sample space : {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18}

Total number of outcomes = 18

1) probability of an even number or a multiple of 3

An even number or a multiple of 3 : {6,12,18}

number of outcomes = 3

$P_{\text{even number or a multiple of 3}}=\frac{3}{18}=\frac{1}{6}$

The probability of the spinner landing on an even number or a multiple of 3 is $\frac{1}{6}$

2) Probability of the spinner landing on an odd number or a number between 4 and 15 (both numbers excluded)

An odd number or a number between 4 and 15 (both numbers excluded):

{5,7,9,11,13}

number of outcomes = 5

$P_{\text{An odd number or a number between 4 and 15}}=\frac{5}{18}$

The probability of the spinner landing on an odd number or a number between 4 and 15 (both numbers excluded) is $\frac{5}{18}$.

Answer 2

The first one would be 2/3 and the second one is the same question, so its 2/3 as well. Hope this helps and let me know if you need an explanation.
