Step-by-step explanation:
Suppose there are 100 kids
60% have fever, so <em><u>what is 60% of 100?</u></em>
We convert percentage to decimal and multiply:
60/100 = 0.6
0.6 * 100 = 60 have fever
20% of the people having fever (60 of them) have sore throats, so,
<u><em>What is 20% of 60?</em></u>
We convert percentage to decimal and multiply:
20/100 = 0.2
0.2 * 60 = 12 have sore throat
So, how many people are there with fever AND sore throat, that is 12. We took initially there to be 100 people. Hence, the probability is:

Step-by-step explanation:
We know that the circumference of a circle is given by :-
, where r is the radius of the circle .
Given : Circumference of circle = 16 cm
Then,
i.e (1)
We know that the area of circle is given by :-
i.e. [From (1)]
i.e.
i.e.
Put
Hence, area of circle =
