Let the probability of success on a Bernoulli trial be 0.26. a. In five Bernoulli trials, what is the probability that there wil

andreyandreev [35.5K]

Answer:

0.3898 = 38.98% probability that there will be 4 failures

Step-by-step explanation:

A sequence of Bernoulli trials forms the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

Let the probability of success on a Bernoulli trial be 0.26.

This means that $p = 0.26$

a. In five Bernoulli trials, what is the probability that there will be 4 failures?

Five trials means that $n = 5$

4 failures, so 1 success, and we have to find P(X = 1).

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{5,1}.(0.26)^{1}.(0.74)^{4} = 0.3898$

0.3898 = 38.98% probability that there will be 4 failures

ioda

Answer:

$3063.6

Step-by-step explanation:

72% of $4,255 = $3063.6

The formula for finding percents is number x percent ÷ 100.

4,255 x 72 ÷ 100 = 3063.6

All of the rings of a ladder are parallel and the top rung is perpendicular to a side of the ladder. What conclusion can be reac

Ronch [10]

Perpendicular sides or lines meet at right angles. The conclusion that can be reached is that:

1. all of the rings are perpendicular to that side.

The statements in the question can be listed as:

Rings in the ladder are parallel
Top ring is perpendicular to the side of the ladder

From statements 1 and 2 above, we understand that;

All other rings in the ladder are parallel to the side ring

This means that the relationship between the top ring and the side of the ladder is the same as the relationship between other rings and the side of the ladder

i.e. the side rings are also perpendicular to the side of the ladder

Hence, the conclusion that can be reached is:

1. all of the rings are perpendicular to that side.
