Rickey got 1199 and Pedro got 1474. I got that by subtracting 275 from 2673 to get 2398. Than you divide 2398 to get 1199 which is Rickey's answer but to get Perdro you have to add 275 to get his answer of 1474.

Julli [10]

Answer:

The formula for the probability distribution is:

P(X = n) = q^(n - 1)p

= [0.2^(n - 1)]0.8

Step-by-step explanation:

This is a geometric probability distribution.

The probability of success p = 80% = 0.8

The probability of failure is q = 1 - p = 0.2

The formula is:

P(X = n) = q^(n - 1)p

= [0.2^(n - 1)]0.8

8) A committee has fifteen members. There are two members that currently serve as the board’s chairman and vice chairman. Each m

pickupchik [31]

Answer:

The probability is $P(Z) = 0.0064$

Step-by-step explanation:

From the question we are told that

The number of members is n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

$K = ^{n}C_2 * 2!$

Here C stands for combination hence we will be making use of the combination functionality in our calculator

$K = ^{15}C_2 * 2 * 1$

=> $K = 78 * 2 * 1$

=> $K = 156$

Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

$P(Z) = \frac{m}{K}$

=> $P(Z) = \frac{1}{156}$

=> $P(Z) = 0.0064$
