You have the numbers 1–25 written on slips of paper. If you choose one slip at random, what is the probability that you will select a number that is divisible by 4?
1/5, 62/25, 4/25, 2/3
4 8 12 16 20 24 is 6 numbers
6/25
If you do not count 4 itself then
5/25 = 1/5
To Damon:
Oh my gosh! Thank you so much. I kept comimg up with 6/25 too, but I knew it wasn't one of the options. It didn't occur to me that 4 might not be included. I really appreciate you pointing tha tout to me. It seems so simple, but I just couldn't get it.
what if not divisible by 4
On each of five slips of paper, you wrote the words , , , , and . Every day, you choose one slip from a jar to help you decide what to eat for breakfast. You always put the chosen slip back into the jar. What is the probability of choosing ?
Well, let's think about it. Out of the numbers 1-25, we know that not all numbers are divisible by 4. In fact, only 6 numbers are divisible by 4: 4, 8, 12, 16, 20, and 24. So out of the 25 available slips of paper, we have 6 slips with numbers divisible by 4.
Now, if you randomly choose one of those slips, what are the chances that you'll get a number divisible by 4? Well, since we have 6 possible successful outcomes out of 25 total outcomes, the probability would be 6/25.
Therefore, the correct answer is 6/25.
To find the probability of selecting a number that is divisible by 4 from the numbers 1-25, we first need to determine the total number of slips that are divisible by 4 and the total number of slips in the given range.
To find the total number of slips divisible by 4, we can start by listing down all the multiples of 4 between 1 and 25, which are: 4, 8, 12, 16, 20, and 24. So, there are 6 slips in total that are divisible by 4.
Next, we need to find the total number of slips in the given range, which is from 1 to 25. Since there are 25 numbers in total, there are 25 slips.
Finally, we can calculate the probability by dividing the number of favorable outcomes (slips divisible by 4) by the total number of possible outcomes (total slips).
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 6 / 25
Therefore, the probability of selecting a number that is divisible by 4 is 6/25.
So, the correct answer is 6/25.
