How many numbers between 1 and 10000 are divisible by 4 ?

freckles · Answer

Think of all the multiples of 4
4(1)=4
4(2)=8
...
4k=10000
figure out what k is to figure out how many multiples of 4 you have between 1 and 10000

@ganeshie8 is it 500?

anonymous · Answer

I multiply 5 and 4 and divide it to 10000 to get 500

A number between 1 and 10000 is randomly selected. What is the probability that it will be divisible to 4 and 5? Based from the question. Am i doin it right?

If 10000 is included the probability is
$$
\frac{500}{10000}=\frac 1 {20}=5\%

$$
