Answer:

P(X = 0) = 0.25

P(X = 1) = 0.75

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability distribution of X.

3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.

P(X = 0) = \frac{1}{4} = 0.25

P(X = 1) = \frac{3}{4} = 0.75

Answer:

Part A) The volume of the entire cone is 168\pi\ in^3

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2}h

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

so

\frac{AB}{AC}=\frac{BD}{CE}

substitute the given values

\frac{7}{14}=\frac{3}{x}

solve for x

x=14(3)/7\\x=6\ in

To find out the volume of the entire cone we have

r=CE=x=6\ in

h=AC=14\ in

substitute in the formula

V=\frac{1}{3}\pi (6)^{2}(14)

V=168\pi\ in^3

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

so

\frac{AB}{AC}=\frac{BD}{CE}

substitute the given values and solve for x
