CUET Mathematics - Let X denote the number of hours a person watches television during a randomly selected day. The probability that X can take the value x_i, has the following form, where k is some unknown constant. P(X=x_i) = cases 0.5 & if x_i=0 \\ kx_i & if x_i=1 \\ k(4-x_i) & if x_i=2 or 3 \\ 0 & otherwise cases The probability that the person watches at most 2 hours of television on a selected day is : | PYQs + Solutions | AfterBoards
