A bag contains 9 red marbles, 5 white marbles, and 6 blue marbles. You draw 4 marbles out at random, without replacement. Find t

IRINA_888 [86]

a) 0.0260

b) 0.0681

Explanation:

The bag contains:

r = 9 (number of red marbles)

w = 5 (number of white marbles)

b = 6 (number of blue marbles)

So, the total number of marbles in the bag at the beginning is:

$n=9+5+6=20$

At the 1st attempt, the probability of choosing a red marble is:

$p(r)=\frac{r}{n}=\frac{9}{20}$ (1)

At the 2nd attempt, the 1st red marble is not placed back, so now the number of marbles is (n-1), while the number of red marbles left is (r-1). So the probability of choosing another red marble at the 2nd attempt is

$p(r)=\frac{r-1}{n-1}=\frac{8}{19}$ (2)

With a similar argument, the probabilities of selecting a red marble in the 3rd and 4th attempt are

$p(r)=\frac{7}{18}$ (3)

$p(r)=\frac{6}{17}$ (4)

Therefore, the probability of drawing 4 red marbles in the first 4 attempts without replacing is:

$p(rrrr)=\frac{9}{20}\frac{8}{19}\frac{7}{18}\frac{6}{17}=\frac{3024}{116280}=0.0260$

At the 1st draw, the probability that the marble is not red is:

$p(r^c)=1-p(r)=1-\frac{9}{20}=\frac{11}{20}$

At the 2nd draw, there are 9 red marbles left and 19 total marble left. So, the probability of NOT drawing a red marble is:

$p(r^c)=1-\frac{9}{19}=\frac{10}{19}$

At the 3rd draw, there are 9 red marbles left and 18 total marbles left. So, the probability of NOT drawing a red marble is:

$p(r^c)=1-\frac{9}{18}=\frac{9}{18}$

Finally, with a similar argument the probability of NOT drawing a red marble at the 4th and last attempt is:

$p(r^c)=\frac{8}{17}$

So, the total probability of drawing 4 non-red marbles in the first 4 attempts is:

$p(r^cr^cr^cr^c)=\frac{11}{20}\frac{10}{19}\frac{9}{18}\frac{8}{17}=\frac{7920}{116,280}=0.0681$

nlexa [21]

Answer:

a) Bonds Payable.

Explanation:

Since there is an issue of bonds as against cash, which need to be paid back in future, amount received will be credited to bonds payable.

Further the purpose of bonds will always be to acquire a capital asset as bonds are issued for long term finance generally, therefore, the bonds will be credited as bonds payable, rather than capital contributions.

Though a general note in notes to account can be added clearly specifying the purpose of issue of bonds.

C. biased, understating the effectiveness of the diet.

This clearly means that the company is trying to sell the product with false reports as the sample size of study is to small to represent entire American Population.

Further that too the employees could be influenced to get the false results.

As since the employees could be influenced and that the results can be altered accordingly, the report is biased, and is misleading.

Nutka1998 [239]

Answer:

Maximum profit = $6

Maximum loss = -$2

Explanation:

The computation of maximum profit and loss for this position is shown below:-

Maximum profit = Strike price - Purchase of stock

= $58 - $52

= $6

Maximum loss = Strike price - Purchase of stock

= $50 - $52

= - $2

Therefore for determining the maximum profit and loss for this position we simply applied the above formulas.
