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.

In how many ways 5 distinct numbers can be selected from the natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 such that atleast one of these 5 is greater than 8

If p and q are chosen at random from the set {1,2,3,4,5,6,7,8,9,10} with replacement. Find the probability that the roots of x^(2)+px+q=0 are imaginary.

In how many ways 5 distinct numbers can be selected from the natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 such that all the 5 are not consecutive

In how many ways 5 distinct numbers can be selected from the natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 such that their product is even

In how many ways 5 distinct numbers can be selected from the natural numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 such that their sum is odd

The points (3,2,-4 ),( 5,4,-6 ) , (9,8,-10 )are

following set is equal or not? A = {3,4,5,6}, B= {7,8,9,10}

If p and q are chosen randomly from the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} with replacement. Find the probability that the roots of the equation x^(2) + px + q = 0 are real.
