What is the probability that a four digit number is divisible by 2?
Even numbers are divisible by two, and half of all numbers are even, so there is a 50 percent chance that a four-digit number is divisible by two.
How many 2 digit numbers are divisible by 5 and 6?
If n is divisible by both 5 and 6, then it should be divisible by 30 (5 * 6). Considering you are asking for only two-digit numbers, the answer(s) would be 30, 60, and 90. So, three numbers.
How many two-digit numbers are divisible by both 9 and 2?
There are five numbers: 18, 36, 54, 72, 90.
What is the sum of all two digit numbers which are divisible by 5?
945
How many four digit numbers which are divisible by 7?
Best way to work this out: find the highest number below 10,000 that is divisible by 7 (9,996) and divide that by 7 (1,428). 1,428 is the amount of one-, two-, three- and four-digit numbers divisible by 7. Now find the number of one-, two- and three-digit numbers divisible by 7 (which is 994/7 = 142) and subtract this number from 1,428, giving us 1,286.
