Solution

Probability formula
probability of an event = $\frac{N u m b e r o f F a v o r a b l e o u t c o m e s}{T o t a l n u m b e r o f p o s s i b l e o u t c o m e s}$

-If $p (A) > p (B)$ then-event A is more likely to
occur than event B.

-If $P (A) = P (B)$ then events A and B are equally
likely to occur.
