In: Statistics and Probability
if A union B = S, A intersect B = empty set, P(A) = x, P(B) = y, and 3x-y = 1/2, find x and y.
Data given:
Now, we can find the values of x and y as -
1.
2. Similarly,
As we know, the formula for P(A U B) is given as -
On adding Equation1 and Equation2, we get -
On substituting the value of x = (3/8) in Equation2, we get -
Thus, the values for x and y are -
