(i) If one person is selected at random, find the probability that he/she travelled by bus or ship.
(ii) Which is most favourite mode of transport and how many people used it?
(iii) (b) The probability that randomly selected person used aeroplane is $\frac{7}{60}$. Find the revenue collected by air company at the rate of ₹$5{,}000$ per person.

Accepted Answer

Step 1: (i) $P(	ext{bus or ship}) = \frac{36 + 33}{360} = \frac{69}{360} = \frac{23}{120}$
Step 2: (ii) Car is the most favourite mode. Number of people who used car $= \frac{177}{360} 	imes 120 = 59$
Step 3: (iii)(b) Number of people who used aeroplane $= \frac{7}{60} 	imes 120 = 14$
Step 4: Revenue collected $= 14 	imes 5000 = $ ₹$70{,}000$
