Consider a situation where p(a) = 4/5 and p(a and b) = 1/2. if the events are independent, then what is p(b)?

Step-by-step explanation:

Since it's independent you use the formula:

P(A) x P(B) = P(A+B)

(4/5) x P(B) = (1/2)

Make common denominator

(8/10) x P(B) = (5/10)

P(B) = 5/8

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
