About 7% of men in the United States have some form of red-green color blindness. Suppose we

Afina-wow [57]

Answer:

<h2>The probability will be $\frac{9538}{37345}$ </h2>

Step-by-step explanation:

<u>Let the total population of United States is 100.</u>

As per the given scenario, among them 7 men have the red-green color blindness.

Among the 4 selected males having at least 1 man having color blindness there could be total 4 possible cases.

CASE 1:

1 of the 4 men having blindness.

The probability will be $\frac{7C1\times93C3}{100C4} = \frac{7\times\frac{93\times92\times91}{6} }{\frac{100\times99\times98\times97}{24} } = \frac{28\times93\times92\times91}{100\times99\times98\times97}$

CASE 2:

2 of the 4 men having blindness.

The probability in this case will be $\frac{7C2\times93C2}{100C4} = \frac{7\times6\times\frac{93\times92}{2} }{\frac{100\times99\times98\times97}{24} } = \frac{56\times93\times92}{100\times99\times98\times97}$

CASE 3:

3 of the 4 men having blindness.

The required probability is $\frac{7C3\times93C1}{100C4} = \frac{7\times6\times\frac{93\times5}{6} }{\frac{100\times99\times98\times97}{24} } = \frac{35\times93\times24}{100\times99\times98\times97}$

CASE 4:

All of the 4 men that will be chosen, have the blindness.

In this case all of the men will be chosen from the 7% of the total population.

Hence, the probability is $\frac{7C4}{100C4} = \frac{7\times6\times5\times4 }{100\times99\times98\times97 } = \frac{35\times24}{100\times99\times98\times97}$

As any of the above 4 cases could be possible, in order to get the desired answer we need to add them.

hence, the answer is $\frac{9538}{37345}$

noreen made 8 2/3 cups of snack mix for a party. her guest ate 3/4 of the mix. how much snack mix did her guest eat?

miskamm [114]

Noreen made 8 and 2/3 cups which after solving becomes 8.666
now the guest ate 3/4 which means 3/4 of 8.66 which is 6.50 which means the guest ate 6 1/2 cups

Write the equation of the parabola in vertex form that has the following properties: passes through the point (2, 12) and has a

tatuchka [14]

Answer:

Step-by-step explanation:

f(x) = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (4, -4) is

f(x) = a(x - 4)² - 4

passes through the point (2, 12) means if x=2 then f(x)=12

12 = a(2 - 4)² - 4

12 +4 = a(-2)² - 4 +4

16 = 4a

a = 4

Therefore the equation (in vertex form) of parabla is:
