List of top Mathematics Questions on Probability asked in AP EAMCET

Two persons A and B throw three unbiased dice one after the other. If A gets the sum 13, then the probability that B gets a higher sum is:
When an unfair dice is thrown, the probability of getting a number \( k \) on it is \( P(X = k) = k^2 P \), where \( k = 1, 2, 3, 4, 5, 6 \) and \( X \) is the random variable denoting a number on the dice. Then, the mean of \( X \) is:
8 teachers and 4 students are sitting around a circular table at random. The probability that no two students sit together is:
Three numbers are chosen at random from 1 to 20. The probability that their sum is divisible by 3 is:
A box contains \(100\) balls, numbered from \(1\) to \(100\). If \(3\) balls are selected one after the other at random with replacement from the box, then the probability that the sum of the three numbers on the balls selected from the box is an odd number, is
In a lottery containing \(35\) tickets, exactly \(10\) tickets bear a prize. If a ticket is drawn at random, then the probability of not getting a prize is
A bag contains \(7\) green and \(5\) black balls. \(3\) balls are drawn at random one after the other. If the balls are not replaced, then the probability of all three balls being green is
If \(x\) is chosen at random from the set \(\{1,2,3,4\}\) and \(y\) is chosen at random from the set \(\{5,6,7\}\), then the probability that \(xy\) will be even is
