Answer:
The maximum revenue will be
at price 
Step-by-step explanation:
Given:

Find the vertex of the parabola represented by given equation:

When
then

The maximum revenue will be
at price 
Since, both the events are independent.
So, P(A+B) = P(A)×P(B)
a) P( Head & Getting a 2 ) = P( head ) × P( Getting a 2 )

b) P( Even number & Tail ) = P( Even number ) × P( Tail )

Hence, this is the required solution.
