Since the events are dependent, the probability of occurrence of event B will impact the probability of occurrence of event A. So we will be using the formula of conditional probability to find P(A ∩ B).

Here P(A*B) indicates P(A ∩ B).
Using the values, we get:
P(A ∩ B) = 0.25 x 0.4 = 0.1
Thus, option A gives the correct answer.

A) because it is 2/3 past 1
Answer:
The solution set is given by {a, -b}.
Step-by-step explanation:
We have the equation,

Equating the factors to 0 gives,
and 
i.e. x = a and x = -b
So, the solutions of the equation
are x= a and x= -b.
Thus, the solution set is given by {a, -b}.
