Question 37 If the letters of the word RAMANUJAN are put in a box and one letter is drawn at random. The probability that the letter is A is (a) 3/5 (b) 1/2 (c) 3/7 (d) 1/3 The word word RAMANUJAN has 1 R, 3 A, 1 M, 2 N, 1 U, 1 J, Total number of letters = 9 Number times A comes = 3 Thus, Probability that the letter is A = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑡𝑖𝑚𝑒𝑠 𝐴 𝑐𝑜𝑚𝑒𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑙𝑒𝑡𝑡𝑒𝑟𝑠) = 3/9 = 𝟏/𝟑 So, the correct answer is (d)
