Vlada [557]

The probability that four or fewer of the people who called will sign up for a class = 0.9805

For given question,

Eric estimates that one out of every five people who call for information about a class will sign up for the class.

Last week he receive nine calls.

We need to find the probability that four or fewer of the people who called will sign up for a class.

Total number of calls = 9

⇒ n = 9

Since one out of every five people who call for information about a class will sign up for the class.

the probability of success (p) = 1/5

= 0.2

and the probability of failure (q) = 1 - p

= 1 - 0.2

= 0.8

To find the probability that four or fewer of the people who called will sign up for a class.

So, x would take values 0, 1, 2, 3, 4

Using Binomial principal,

For x = 0,

$P(x=0)= ~^9C_0(0.2)^0(0.8)^{9-0}\\\\P(x=0)=0.13422$

For x = 1,

$P(x=1)= ~^9C_1(0.2)^1(0.8)^{9-1}\\\\P(x=1)=0.30199$

For x = 2,

$P(x=2)= ~^9C_2(0.2)^2(0.8)^{9-2}\\\\P(x=2)=0.30199$

For x = 3,

$P(x=3)= ~^9C_3(0.2)^3(0.8)^{9-3}\\\\P(x=3)=0.17616$

For x = 4,

$P(x=4)= ~^9C_4(0.2)^4(0.8)^{9-4}\\\\P(x=4)=0.06606$

So, the required probability would be,

P = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4)

P = 0.1342 + 0.3020 + 0.3020 + 0.1762 + 0.0661

P = 0.9805

Therefore, the probability that four or fewer of the people who called will sign up for a class = 0.9805

Answer:

2 is not the same as 4.

$2^2$ is the same as 4, since 2*2 = 4.

Find the area of semi-circle whose radius is 'm' units.

Sav [38]

Radius of the circle = m units
Therefore, area of the circle $= \pi \: {m}^{2} square \: \: units$
We know, semi-circle is half of a circle.
So, the area of the semi-circle $= \frac{\pi \: {m}^{2} }{2} \: square\: \: units$

Answer:

$\frac{\pi \: {m}^{2} }{2} \: square\: \: units$

Hope you could understand.
