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 a odd number which is multiple of 11?

Answer»

<P>0.05
0.1
0.12
0.06

Solution :Favourable outcomes are {11, 33, 55, 77, 99}. Number of favourable outcomes is 5. Therefore
`n(E_(3))=5`
P(odd number MULTIPLE of 11),
`P(E_(3))=(n(E_(3)))/(n(S))=(5)/(100)=0.05`
Thus (a) is correct option.
