The probability is very close to 0.25 A year is a leap year if the number is divisible by 4 - except if the number is divisible by 100 it is not a leap year - except if the number is divisible by 400 it is a leap year. So, in a 400-year period there are 97 leap years. The probability or relative frequency of leap years is, therefore, 97/400 = 0.2425
50 50 odd or even same probability
The probability is 67/200.
On a single roll is it 2/3.

If the die is fair then for a single roll, the probability is 1/2.
2/6 or 1/3
On a single roll is it 2/3.

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.
Well, numbers divisible by 2 are even numbers, and the even numbers from 1 to 6 are 2,4,and 6. Since there are 3 out of 6 even numbers on a number cube, there is a probability 1/2 to roll an even number on a number cube.

You carry out an experiment repeatedly. Then the number of times that the selected even occurs divided by the total number of trials is the relative probability for that event.
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%.
