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
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.
