A real estate agent has 1717 properties that she shows. She feels that there is a 60`% chance of selling any one property during

Pavlova-9 [17]

Answer:

$P(x \le 5) = 0.0110$

Step-by-step explanation:

Given

$n = 17$ -- number of properties

$p = 60\%$ --- probability of selling a property

Required

$P(x \le 5)$

The question is an illustration of binomial probability, and it is calculated using:

$P(x ) = ^nC_x * p^x * (1 - p)^{n-x}$

So, we have:

$P(x \le 5) = P(x = 0) +P(x = 1) +P(x = 2) +P(x = 3) +P(x = 4) +P(x = 5)$

$P(x=0 ) = ^{17}C_0 * (60\%)^0 * (1 - 60\%)^{17-0} = 1.71798692*10^{-7}$

$P(x=1 ) = ^{17}C_1 * (60\%)^1 * (1 - 60\%)^{17-1} = 0.00000438086$

$P(x=2 ) = ^{17}C_2 * (60\%)^2 * (1 - 60\%)^{17-1} = 0.00005257039$

$P(x=3 ) = ^{17}C_3 * (60\%)^3 * (1 - 60\%)^{17-3} = 0.00039427799$

$P(x=4 ) = ^{17}C_4 * (60\%)^4 * (1 - 60\%)^{17-4} = 0.00206995948$

$P(x=5 ) = ^{17}C_5 * (60\%)^5 * (1 - 60\%)^{17-5} = 0.008072842$

So, we have:

$P(x \le 5) = 1.71798692*10^{-7}+0.00000438086+0.00005257039+0.00039427799+0.00206995948+0.008072842$

$P(x \le 5) = 0.01059420251$

$P(x \le 5) = 0.0110$
