Answer:
Okay, let's solve this step-by-step:
There is a spinner with 14 equal areas, numbered 1 through 14
We want to find the probability that the result is a multiple of 3 or a multiple of 4
There are 14 possible outcomes (numbers 1 through 14) when the spinner is spun.
Of these 14 numbers:
4 are multiples of 3: 3, 6, 9, 12
4 are multiples of 4: 4, 8, 12, 16
However, 12 is also a multiple of both 3 and 4, so we have counted it twice.
We need to subtract 1 from each to account for this:
Multiples of 3: 3
Multiples of 4: 4
So there are 3 possible multiples of 3 and 3 possible multiples of 4.
In total, there are 3 + 3 = 6 possible multiples of 3 or 4.
To calculate probability:
Probability = (Number of favorable outcomes) / (Total possible outcomes)
= 6 / 14
= 3/7
Converting to a percent: 3/7 = 42.9%
Rounded to the nearest whole percent: 43%
Therefore, the probability that the result is a multiple of 3 or a multiple of 4 is 43%.
