(a) In a lottery, there are 10 prizes and 20 blanks. A ticket is chosen at random, what is the probability of getting a prize?

(b) Study the following pictograph and answer the questions given below it.

(i) How many cars were produced in the month of July?

(ii) In which month were maximum number of cars produced?

Answer:

(a) Since, total no. of outcomes = 10 + 20 = 30

Probability of an event,

\[P(E)\text{ }=\frac{Favourable\text{ }outcomes}{Total\text{ }number\text{ }of\text{ }outcomes}\]

Then,   P (getting a prize) =                                                         \[=\frac{10}{30}=\frac{1}{3}\]

250 cars were produced in the month of July.

Maximum number (= 400) of cars were produced in the month of September.
