If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:

P(AorB)=P(A)+P(B) 
P(AorB)=\frac{40}{61}+\frac{2}{61} 
P(AorB)=\frac{42}{61} 
P(AorB)\approx 68.8\% 

A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.

Solve for p, w = Q+P<br> -------<br> Q-QP
7nadin3 [17]
Alright, here it is
w=(q+p)/(q-pq)
factor out the q in the bottom part

w=(q+p)/[(q)(1-p)]
multiply both sides by q
wq=(q+p)/(1-p)
add 1 to both sides, but add (1-p)/(1-p) to the right side since that equals 1
wq+1=(q+1+p-p)/(1-p)=(q+1)/(1-p)
multiply both sdies by (1-p)
(wq+1)(1-p)=q+1
divide both sdies by (wq+1)
1-p=(q+1)/(wq+1)
subtract 1 from both sdies
-p=[(q+1)/(wq+1)]-1
multiply by -1
p=-[(q+1)/(wq+1)]+1 or
p= -\frac{(q+1)}{(wq+1)}+1

Frankie wants to build a path from one corner of his yard to the opposite corner. His yard measures 20 ft. x 32 ft. What will be
riadik2000 [5.3K]
Frankie's yard is a rectangle with the longer side = 32ft and the shorter side = 20ft. You want to find the length of the diagonal going through the rectangle. In essence, you basically have a triangle with two sides, one 32ft, the other 20ft, and you're looking for the hypotenuse.

Let's call a=32, b=20, and you're looking for the hypotenuse c. Use the Pythagorean theorem:
{a}^{2}  +  {b}^{2}  = {c}^{2}
Plug the numbers in to find c, the length of your path! So
\sqrt{{32}^{2}  +   {20}^{2}}  = 37.7

Nathan usually drinks 36 ounces of water per day he read that he should drink 64 ounces of water per day if he starts drinking 6
Luden [163]
First determine how much it increased by. 36+X=64
X=28

It increased by 28

Now determine what percentage 28 is of 36
36(Y)=28
Y=.77777778

28 is a 77.78% (.7778) increase from 36

After you round, your answer is 78%
