To find the probability of rolling an even number or an odd prime number, we first need to determine the total number of outcomes that meet the criteria.
There are 8 even numbers on a sixteen-sided number cube: 2, 4, 6, 8, 10, 12, 14, 16.
There are 5 odd prime numbers on a sixteen-sided number cube: 3, 5, 7, 11, 13.
However, we need to exclude 1 from the prime numbers, so the total number of outcomes that meet the criteria is 8 (even numbers) + 5 (odd prime numbers) - 1 = 12.
The total number of sides on the number cube is 16.
Therefore, the probability of rolling an even number or an odd prime number is:
12/16 = 0.750.
Rounded to three decimals, the probability is 0.750.
Therefore, the answer is: 0.750.
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 primeRound to three decimals. (1 point) 0.188 0.813 0.219 0.156
