The probability to pass in an examination of mathematics for three students are `1/4,1/5,1/6`. Find the probability that at least two students will pass in this examination.

The probability student A passing an examination is (3)/(5) , student B passing an examination is (4)/(5) . Find the probability only one of them will pass the examination, assuming the events 'A passses and 'B passes' are independent.

The probability that a student will pass his examination is 0.73, the probability of the student getting a compartment is 0.13 and the probability that the student will either pass or get compartment is 0.96.

The probability of' the solving a problems in mathematics of three students are 1/3,1/5,1/6 . If they try to solve the problem together, find the probability that the problem is solved by at least one student.

A student has appeared for an examination. There are 20 question in the paper, with four multiple answer. If he answers correctly he gets 4 marks and if the answer is wrong he gets - 1 mark. A Student will pass in the examination if he gets 50% of the marks.If a student answers by sheer guessing, then the probability that he will pass in the examination is
