Question

Length and breadth of a rectangular
garden are 77 m and 50 m. There is
a circular lake in the garden having
diameter 14 m. Due to wind, a towel
from a terrace on a nearby building fell
into the garden. Then find the
probability of the event that it fell in
the lake.​

Answer 1

area of total rectangular garden is 77×50=3850

area of circular lake = πr*r

where r is 14/2=7

=154

:hence the prob. is 154/3850 i.e: 0.04
