If p(a)=1/3, p(b)=2/5, and p(aub)=3/5, what is p(a^b)?

The probability of the union of two events is the sum of their probability, minus the probability of their interserction:

If we plug the known values into this formula, we have

From which we can deduce

So, the probability of is a bit less than , we have to take away all events that belong to B as well:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
