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 less than 70 ?

Options

A. 0.13
B. 0.14
C. 0.12
D. 0.15

Answer

D

Explanation

Favourable outcomes are 71, 73, 75, …….99.
Number of favourable outcomes, `n(E_(4))=15`
P(odd number not less than 70),
`P(E_(4))=(n(E_(4)))/(n(S))=(15)/(100)=0.15`
Thus (d) is correct option.
