What is the probability of a number that is selected randomly from the set of integers between one and fifty to be divisible by 7?
If we include both 1 and 50 there are 50 numbers to choose from. The numbers that are divisible by 7 in that range are 7, 14, 21, 28, 35, 42,and 49. There are 7 of them. So the answer would be 7 out of 50, which is 14%.
Divisibility pattern for 7?
you have to separate them and if both of them are in the 7 times table it is. eg.3521 is it divisible by 7 35 + 21 the 35 is in the 7 timetable and so is the 21 so there both divisible by 7. another eg.1442 14 + 21 14 is divisible by 7 and so is 21 yes it is . thank u
