Question

Using a sixteen-sided number cube, what is the probability that you will roll an even number or an odd prime number? The number 1 isn't an odd prime. Round to three decimals.

Answer 1

hiii :)

Answer 2

Hello. Can you help me?

Answer 3

3,5,7,11,13 = 5 numbers + 8 even numbers = 13
13/16 is the probability

Answer 4

do u understand?

Answer 5

The answer choices are: 0.188, 0.813, 0.219, and 0.156

Answer 6

check wat 13/16 is

Answer 7

0.8125?

Answer 8

yep your question says round to 3 decimal places so what will that be

Answer 9

I'm not sure :/

Answer 10

0.813?

Answer 11

well this is how you round numbers
0.8125 right
so you look at the last digit in that number
if the number is 5 or more like 0.8126 you say it is closer to 0.813 than it is closer to 0.812 so you
make it 0.813
if it 4 or less like 0.8124 then you say its closer to 0.812 than 0.813 make it 0.812

Answer 12

So, the answer is 0.813?

Answer 13

yes and do you want to know why 13/16 gave us that answer

Answer 14

Yes.

Answer 15

okay ummm
this is how you do it

you want to know if you roll the dice then what are the chances it will be either a prime number or even number on a 16 sided dice right

Answer 16

that means dice numbers go like this
1 <---- this number they say is not an odd prime so we dont take it
2 <--even
3---prime
4 even
5 prime
6 even
7 prime
8 even
9
10 even
11 prime
12 even
13 prime
14 even
15
16 even
now count up all the even and prime that is 8 even and 5 prime so 8+5 = 13

now there are 16 sides to a dice so 16 outcomes but we only need 13
so to get 13 out of those 16 outcomes or in math terms that is 13/16 which means 13 out of 16

Answer 17

anything not make sense?
