So than you check this graph so you see that the radius has a length of 4 units
from what result that thet x^2 +y^2 =4

so the choice 3rd is right sure

A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 50% of this population prefers t

mihalych1998 [28]

Answer:

$P(X=10) = 0.1222$

Step-by-step explanation:

Represent Green with G

So,

$G = 50\%$

Required

Determine the probability that 10 out of 16 prefer green

This question is an illustration of binomial distribution and will be solved using the following binomial distribution formula.

$P(X=x) = ^nC_xG^x(1-G)^{n-x}$

In this case:

$n = 16$ -- number of people

$x = 10$ -- those that prefer green

So, the expression becomes:

$P(X=10) = ^{16}C_{10}G^{10}(1-G)^{16-10}$

$P(X=10) = ^{16}C_{10}G^{10}(1-G)^{6}$

Substitute 50% for G (Express as decimal)

$P(X=10) = ^{16}C_{10}*0.50^{10}*(1-0.50)^{6}$

$P(X=10) = ^{16}C_{10}*0.50^{10}*0.50^{6}$

Apply law of indices

$P(X=10) = ^{16}C_{10}*0.50^{10+6$

$P(X=10) = ^{16}C_{10}*0.50^{16$

Solve 16C10

$P(X=10) = \frac{16!}{(16-10)!10!} *0.50^{16$

$P(X=10) = \frac{16!}{6!10!} *0.50^{16$

$P(X=10) = \frac{16*15*14*13*12*11*10!}{6!10!} *0.50^{16$

$P(X=10) = \frac{16*15*14*13*12*11}{6!} *0.50^{16$

$P(X=10) = \frac{16*15*14*13*12*11}{6*5*4*3*2*1} * 0.50^{16$

$P(X=10) = \frac{5765760}{720} * 0.50^{16$

$P(X=10) = 8008 * 0.50^{16$

$P(X=10) = 8008 * 0.00001525878$

$P(X=10) = 0.12219231024$

$P(X=10) = 0.1222$

<em>Hence, the required probability is 0.1222</em>
