A game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers 1,2,3,4,5,6,7,8 (See figure), and these are equally likely outcomes. What is the probability that it will point at (i) 8 ? (ii) an odd number? (iii) a number greater than 2? (iv) a number less than 9?

Seven digits from the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 are written in random order. Find the probability that the seven digited number is divisible by 9.

One number is selected from the four digit numbers that can be formed from the digits 1,2,3,4,5,6,7. The probability that it is an odd number is

Out of numbers 1,2,3,….9, two numbers are chosen at random, so that their sum is an even number. The probability for the two chosen numbers to be odd is

Six faces of an unbaised die are numbered with 2,3,5,7,11 and 13. If two such dice are thrown , then the probability that the sum on the uppermost faces of the dice is an odd number is

Find the mode of the given set of numbers 2,3,5,3,4,7,3,2,1,7,3.

Five digit numbers can be formed from the digits 1,2,3,4,5. If one number is selected at random , the probability that it is an even number is
