if A union B = S, A intersect B = empty set, P(A) = x, P(B)...

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.

Solutions

Expert Solution

Data given:

Now, we can find the values of x and y as -

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 -

Let S be a set and P be a property of the elements of the set, such that each element either has property P or not. For example, maybe S is the set of your classmates, and P is "likes Japanese food." Then if s ∈ S is a classmate, he/she either likes Japanese food (so s has property P) or does not (so s does not have property P). Suppose Pr(s has property P) = p for a uniformly...
