Cards on which numbers 1, 2, 3 .......... 100 are written (one number on one card and no number is repeated), put in a bag and are mixed thoroughly. A card is drawn at random from the bag. Find the probability that card taken out has What is the probability that card taken out has an odd number which is not multiple of 11 ? |
Answer» Solution :Total odd number are 50 and out of which {11, 33, 55, 77, 99} are multiple of 11. Thus 50 - 5 = 45 NUMBERS are multiple of 11. Therefore `""n(E_(5))=45` P(odd number not multiple of 11), `P(E_(5))=(n(E_(5)))/(n(S))=(45)/(100)=0.45` Thus (d) is correct option. |
