2 Q6. A two digit number isformed with digits 2,3,5,7,9without repetition what is theprobability that the numberformed is a multiple of 5?​

Answer»

P(E) = 1/5Step-by-step explanation:let 's' be the all possibilitiess = { 23, 25, 27, 29, 32, 35, 37, 39, 52, 53, 57, 59, 72, 73, 75, 79, 92, 93, 95, 97}n(s) = 20let 'E' be the event of a multiple of 5 being formedE = { 25, 35, 75, 95 }n(E) = 4 P(E) = n(E)/n(s) = 4/20 = 1/5thus, probability is 1/5.
