a spinner has the number 1 through 9. the spinners is spun once. what is the probability of p(3,6,8). write as a percent
If P(3,6,8) means 3 or 6 or 8, then either-or probabilities are found by adding the individual probabilities (1/9).
If P(3,6,8) mean 3 then 6 and then 8, if the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
To find the probability of landing on a specific outcome, divide the number of favorable outcomes by the total number of possible outcomes.
In this case, we are looking for the probability of landing on the numbers 3, 6, or 8. Since the spinner has numbers 1 through 9, the total number of possible outcomes is 9.
Out of these 9 numbers, there are 3 numbers (3, 6, and 8) that meet our criteria. Therefore, the number of favorable outcomes is 3.
To calculate the probability, divide the number of favorable outcomes by the total number of possible outcomes:
P(3,6,8) = 3/9
Now, to express the probability as a percent, we can multiply this fraction by 100:
P(3,6,8) = (3/9) * 100 = 33.33%
Therefore, the probability of landing on 3, 6, or 8 when spinning the numbered spinner once is 33.33%.
