<h3>Answer:  1/8</h3>

Explanation:

The only way to get a difference of 2 is to draw a "3" and then a "5" in either order.

The probability of selecting any tile is 1/4. The probability of selecting two particular tiles in a row is (1/4)*(1/4) = 1/16 since we replaced the first tile selected.

2*(1/16) = 1/8 represents the probability of selecting a 3 and 5 in either order.

If NO =17 and NP= 5x-6, find they value of x. Then find NP and OP
CaHeK987 [17]

<em>Greetings from Brasil...</em>

We notice 2 dashes on the NO and NP line. This means that both are the same size. Since NO = 17 then OP is also 17 in length.

So

NP = NO + OP

NP = 17 + 17

NP = 34

As already said

NP = 5X - 6 = 34

5X - 6 = 34

<h2>X = 8</h2>

First note that \frac{2^n+1}{2^{n+1}} =  \frac{2^n}{2^{n+1}} + \frac{1}{2^{n+1}} = \frac{1}{2} + \frac{1}{2^{n+1}}

If you take limit, then you have \lim_{n \to \infty}( \frac{1}{2} + \frac{1}{2^{n+1}})= \lim_{n \to \infty}( \frac{1}{2}) +\lim_{n \to \infty}(\frac{1}{2^{n+1}})=\frac{1}{2} +0= \frac{1}{2}
