There is a bag filled with 4 blue, 3 red and 5 green marbles.
zhannawk [14.2K]

Answer:

You are selecting marbles with replacement. The marble selections (trials) are independent and the marble selection follows the binomial distribution.

The probability of selecting a red marble the first time is 1313.

(This is because 4 out of 12 marbles are red and412412 reduces to 1313.

The probability of selecting a red marble the second time is 1313.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds = (13)2(13)2

=19=19.

So the probability of getting two reds is 1919.

QUESTION 3 of 10: Stock returns vary from year to year. The more variance a stock displays the greater the potential risk. These
Dahasolnce [82]

Answer:

The variance of these investment returns is 74

Step-by-step explanation:

Given:

Series =  10, 30, 15, 5, 20

To Find:

variance of a series = ?

Solution:

The variance of the series = Var\left(X\right)=\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n}

\bar{x} = \frac{10+30 +5+15 + 20}{5}

\bar{x} = \frac{80}{5}

\bar{x} =16

Now (x_i -\bar{x})^2 = (10 -16)^2 + (30 -16)^2 + (5 -16)^2 +(15 -16)^2 +(20 -16)^2

= (-6)^2 + (14)^2 + (-11)^2 + (-1)^2+ (-4)^2

= 36  + 196 +121 +  1+ 16

=  370

Now

Var\left(X\right)=\frac{370}{5} =  74
