Look at the adjoining circle graph and answer the following questions.
(i) What is the central angle corresponding to the activities "school and home work"?
(ii) Find the fraction of the circle representing each of these given information.
(i) Since, the total angle at the centre = 360°
i.e. The central angle corresponding to 24 hours = 360°
∴ Central angle form school =
=
Central angle for home work =
=
(ii) Fraction of the circle corresponding to:
Sleeping hours =
Schooling hours =
Playing hours =
Home-work hours =
Other activities hours =
Numbers 1 to 10 are written on ten separate cards such that one number on one slip. These are mixed well and one slip is chosen from the box without looking into it. What is the probability of:
(i) getting a card on which 7 is written?
(ii) getting a card having two-digit number on it?
(iii) getting a number less than 5?
(iv) getting a number more than 5?
When a die is thrown, list the outcomes of an event of getting:
(i) A number less than 5.
(ii) A composite number.
(iii) A prime number.
(iv) A number more than 3.
