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 ?

Answer»

0.25
0.49
`0.50`
0.51

Solution :There are 100 cards in bags. THUS we have 100 possible outcomes for all cases.
`N(S)=100`
Odd NUMBERS 1 to 100 are 50.
NUMBER of favourable outcomes,
`n(E_(1))=50`
P(an odd number),
`P(E_(1))=(n(E_(1)))/(n(S))=(50)/(100)=(1)/(2)`
Thus ( c ) is correct option.
