0.85 is the probability that you will roll an even number or odd prime number
It is a branch of mathematics that deals with the occurrence of a random event.
A twenty-sided number cube has 10 even numbers (2, 4, 6, 8, 10, 12, 14, 16, 18, 20) and 7 odd prime numbers (3, 5, 7, 11, 13, 17, 19).
To find the probability of rolling an even number or an odd prime number
We need to calculate the total favorable outcomes (even numbers and odd prime numbers) divided by the total possible outcomes (numbers 1 to 20).
Total favorable outcomes = 10 (even numbers) + 7 (odd prime numbers) = 18
Total possible outcomes = 20
Probability = Total favorable outcomes / Total possible outcomes = 17 / 20 = 0.9
Hence, 0.85 is the probability that you will roll an even number or odd prime number

Answer:
0.85
Step-by-step explanation:
total samples cases = 20
chances that are even or odd prime are 17 chances
2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, 19, 20
probability = 17/20
= 0.85
