(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.
