Solution

The correct option is B
$\frac{3}{5}$

Probability is a measure of the likelihood of an event to occur. The formula of probability is
Probability of event to happen P(E) $= \frac{N u m b e r o f f a v o u r a b l e o u t c o m e s}{T o t a l N u m b e r o f o u t c o m e s}$
Probability $= \frac{N u m b e r o f t i m e s h e a d a p p e a r e d}{T o t a l n u m b e r o f t i m e s c o i n i s t o s s e d} = \frac{120}{200} = \frac{12}{20}$

On simplifying
$= \frac{3}{5}$
