Cards marked with number 13 , 14 , 15,...60 placed in box and mixed one card is drawn at random for box . find the probability that number on drawn card is divisible by 3 . number which is perfect square

Let S be the sample space.S = 13, 14, 15, ......60nS = 48.1.Let E be the event of getting a card bearing a number divisible by 3.E = 15,18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60nE = 16pE = nEnS = 1648 = 132.Let F be the event of getting a card bearing a number that is a perfect square.F = 16, 25, 36, 49nF = 4now, pF = nFnS = 448 = 112
