School band sold 30 raffle tickets each ticket is labeled with a number 1 to 31 winning ticket will be drawn what is the probabi
Setler [38]

Answer:

0.27

Step-by-step explanation:

To solve this problem, we will use Set Theory Approach to Probability.

Let U = the Sample Space which consists of all possible tests.

Of course U = {1,2,3 .... ,30}

So, no elements in that.

U = n = 30

Let Q = the event bearing a multiple of 4 No winning ticket, and,

R = the case that has the No. 19 winning ticket

∴

Q  = { 4,  8, 12 , 16 , 20, 24 , 28} ,  and

R  = {19} , so that

Q ∩ R  = ϕ

P(Q ∩R ) = 0

As, n(Q) = 7 , n(R) = 1  , we have,

P (Q) = \frac{n (A)}{n(U)} = \frac{7}{30},  and P (R) = \frac{1}{30\\}

P (Q∪R) = P(Q ) + P(R) − P(A∩B) = \frac{7}{30} +  \frac{1}{30\\} − 0 = \frac{8\\}{30\\}

≅ 0.27 .

No you would not use the Pythagorean Theorem, You would take the two sides and multiply them together, and divide it by 2.
