You flip a coin and use a random numer generator to generate a number 1 to 8. What is the probability that the coin shows tails

larisa [96]

probability of getting a tail , PA = 1/2

probability of gettin a number 2 , PB = 1/8

now ,

the probability to get tail and 2 = PA x PB = 1/2 x 1/8 = <u>1/16</u>.

hence it's the answer.

G prove that limx→∞(x 2 + 1)/x2 = 1 using the definition of limit at ∞.

Maslowich

$\displaystyle\lim_{x\to\infty}\frac{x^2+1}{x^2}=1$

means to say there is some number $M$ for which any choice of $\varepsilon>0$ such that

$x>M\implies\left|\dfrac{x^2+1}{x^2}-1\right|$

Working backwards, we have

$\left|\dfrac{x^2+1}{x^2}-1\right|=\left|1+\dfrac1{x^2}-1\right|=\dfrac1{x^2}$
$\implies\sqrt{\dfrac1{x^2}}$

So, whenever $x>M=\dfrac1{\sqrt\varepsilon}$ , we can always guarantee that $\left|\dfrac{x^2+1}{x^2}-1\right|$ .
