if in a spinner of 1-8
if the probability of even numbers is 4/8 and probability of multiple of 3 is 2/8. isn't the answer 6/8/
multiple of 3 are 3,6
so the probability is 2/8
i know but the question is to find the probability of even number from 1-8 which is 4/8 and multiples of 3 from 1-8 which is 2/8. so if you add them isn't the answer 6/8
Don't blame saiko, you didn't even ask the correct question originally
so you want the prob( the number is even And multiples of 3)
the evens are 2 4 6 8
multiples of 3 are 3 6
so the only number which is even and is a multiple of 3 is the number 6
so the prob(of your event) = 1/8
if your sentence would contain the word OR, then there would be 5 numbers, and the
prob = 5/8
What is the actual question?
The real answer is 69

To determine the probability of certain events, we can use the formula:
Probability = Number of favorable outcomes / Total number of outcomes
In this case, let's break down the problem into two parts: the probability of even numbers and the probability of multiples of 3.
1. Probability of even numbers:
The spinner has the numbers 1 to 8. Out of these, the even numbers are 2, 4, 6, and 8, which means there are 4 favorable outcomes (even numbers). The total number of outcomes is 8 since there are 8 numbers on the spinner. Thus, the probability of getting an even number is:
Probability of even numbers = 4 / 8 = 1/2
2. Probability of multiples of 3:
The multiples of 3 in the spinner are 3 and 6, which means there are 2 favorable outcomes (multiples of 3). Again, the total number of outcomes is 8. Thus, the probability of getting a multiple of 3 is:
Probability of multiples of 3 = 2 / 8 = 1/4
As we calculated, the probability of getting an even number is 1/2, and the probability of getting a multiple of 3 is 1/4. However, the question asked for the probability of even numbers or multiples of 3. To find this probability, we can add the probabilities of the two events:
Probability of even numbers or multiples of 3 = Probability of even numbers + Probability of multiples of 3
Probability of even numbers or multiples of 3 = 1/2 + 1/4
To add fractions, we need a common denominator, in this case, it is 4. Therefore:
Probability of even numbers or multiples of 3 = (2/4) + (1/4) = 3/4
So, the correct answer is 3/4, not 6/8.
