Solution

The correct option is **A**

Given,

Total area of the village = 200km2

Each civilization occupies an area of 50km2 because 2004km2=50km2

⇒ Area occupied by Indians = Area occupied by Egyptians = Area occupied by Europeans =Area occupied by Australians = 50km2

Area occupied by Indians and Europeans = 50km2+50km2 =100km2

Probability of an event, P(E) = =number of favourable outcomestotal number of outcomes

Probability that the person lands on a land occupied by Indians or Europeans = 100200 = 12
