A unit test is selected at random. What is the probability that the student gets more than 60% marks in the test ?

Total number of unit tests: 6


Number of Unit tests in which, the student got more than 60%: 2


That includes 1.) unit test II and


2.) unit test V


Probability P() =


1.Let P(U) be probability of Student scoring more than 60% in unit tests


P (U) =


P (U) = =
