Illusion [34]

Answer:

The right answer is:

(a) 0.1456

(b) 18.125, 69.1202, 8.3139

Step-by-step explanation:

Given:

N = 24

n = 5

r = 7

The improperly drilled gearboxes "X".

then,

⇒ $P(X) = \frac{\binom{7}{x} \binom {17}{5-x}}{\binom{24}{5}}$

(a)

P (all gearboxes fit properly) = $P(x=0)$

= $\frac{\binom{7}{0} \binom{17}{5}}{\binom{24}{5}}$

= $0.1456$

(b)

According to the question,

$X = 91+5$

Mean will be:

⇒ $\mu = E(x)$

$=E(91+5)$

$=9E(1)+5$

$=9.\frac{nr}{N}+5$

$=9.\frac{5.7}{24} +5$

$=18.125$

Variance will be:

⇒ $\sigma^2=Var(X)$

$=V(9Y+5)$

$=81.V(Y)$

$=81.n.\frac{r}{N}.\frac{N-r}{N}.\frac{N-n}{N-1}$

$=81.5.\frac{7}{24}.\frac{24-7}{24}.\frac{24-5}{24-1}$

$=69.1202$

Standard deviation will be:

⇒ $\sigma = \sqrt{69.1202}$

$=8.3139$

3/4th of 2.8gigs is already downloaded meaning 75% of it is downloaded. since there's four boxes and the downloading file is up to 3 boxes it gives you 3/4. so all you have to do is multiply .75x2.8 and the answer is 2.1
