anonymous · Answer

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.

how many numbers does the cube have in total?

anonymous · Answer

6

amistre64 · Answer

anonymous · Answer

Wait no lol @amistre64

amistre64 · Answer

lets assume it has 16 numbers :)

how many are going to be even?

how many are prime?  excluding 1 and 2

amistre64 · Answer

add up the number of evens, and the number of primes, and divide by 16

Thats what i did earlier before i posted this question and didnt get any of my answer is my answer practice choice.

amistre64 · Answer

well, what answer did you come up with?  you might simply be miscounting

amistre64 · Answer

assuming we start at 1 and go to 16, that would be 8 evens

primes are then 3,5,7,11,13 ... or 5 of them

so 13/16 is what i get
