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 two digit odd number ?

Answer»

0.23
0.45
0.56
0.34

Solution :TOTAL odd number are 50 and 5 numbers are one digit odd number. Hence TWO digit odd number are 45. Thus favourable OUTCOMES,
`n(E_(2))=50-5=45`
P(Two digit odd number),
`P(E_(2))=(n(E_(2)))/(n(S))=(45)/(100)=0.45`
Thus (b) is CORRECT option.
