Which of the following is a certain event?
A. Rolling a composite number on a number cube
B. Rolling a number greater than 1 on a number cube
C. Rolling an odd or even number on a number cube
D. Rolling a number greater then 7
Thx Dude
All numbers are either odd or even.
Welcome
so is it C?
ya mabe ba
bruh it C
To determine which of the given events is certain, we need to understand the meaning of each event.
A. Rolling a composite number on a number cube: A composite number is any number greater than 1 that has more than two distinct positive divisors. To find out if rolling a composite number is a certain event, we need to identify the number of composite numbers that can be rolled on a number cube.
B. Rolling a number greater than 1 on a number cube: This event implies that rolling any number greater than 1 is considered a success. To determine if this event is certain, we need to determine if all the numbers on a number cube are greater than 1.
C. Rolling an odd or even number on a number cube: This event allows for either an odd or even number to be rolled. To determine if this event is certain, we need to see if all numbers on a number cube are either odd or even.
D. Rolling a number greater than 7: This event implies that only numbers greater than 7 are considered a success. We need to determine if all the numbers on a number cube are greater than 7 to determine the certainty of this event.
To evaluate these events, we need to know the number of sides on a number cube. Usually, a number cube has six sides with numbers 1, 2, 3, 4, 5, and 6. Using this information, we can evaluate each event.
Event A: To determine if rolling a composite number is a certain event, we examine the numbers on a number cube (1, 2, 3, 4, 5, 6). Since numbers 4 and 6 are composite, rolling a composite number is not a certain event.
Event B: All numbers on a number cube are greater than 1. Therefore, rolling a number greater than 1 is certain.
Event C: A number cube includes both odd and even numbers (1, 2, 3, 4, 5, 6). Therefore, it is certain to roll either an odd or even number.
Event D: All the numbers on a number cube are less than or equal to 6. Therefore, rolling a number greater than 7 is not a certain event.
Based on the analysis, the certain event is B. Rolling a number greater than 1 on a number cube.
