The probability that a randomly-selected 2 year old male salamander will live to be three years old is 0.9 567 what is the possibility probability that two randomly selected two year old male salamanders with live to be three years old? what is the probability that nine randomly selected 2-year old male salamanders will live to be 3-years old? what is the probability that at least one of the nine randomly selected 2-year old male salamanders will not live to be 3 years old? would it be unusual if at least one of nine randomly selected 2 year old male salamanders did not live to be 3 years old?

a. Probability = 0.9153

b. Probability = 0.6714

c. $P(atleast\ one) = 0.99999999999$

d. It is not unusual

Step-by-step explanation:

Represent the given probability with P(T)

P(T) = 0.9567

Solving (a): Probability two selected will live to be three years old

This is calculated as:

Probability = P(T) * P(T)

Probability = 0.9567 * 0.9567

Probability = 0.91527489

Probability = 0.9153 --- Approximated

Solving (b): The probability that nine selected will live to be three years old

This is calculated as:

Probability = (P(T))^9

Probability = 0.9567^9

Probability = 0.67140097202

Probability = 0.6714 --- Approximated

Solving (c): Probability that at least one of the nine selected will not live to be three years old

To solve this, we need to determine the probability that none of the 9 selected will live to be 3 years old.

But first, we need to solve the probability that a selected male will not live to be 3 years old.

This is represented as: P(T') and is calculated as thus:

P(T) + P(T') = 1

P(T') = 1 - P(T)

P(T') = 1 - 0.9567

P(T') = 0.0433

The probability that none of the nine will live to be 3 years old is:

P(none) = (P(T'))^9

P(none) = 0.0433^9

So, the required probability is calculated as thus;

$P(atleast\ one) = 1 - P(none)$

$P(atleast\ one) = 1 - 0.0433^9$

$P(atleast\ one) = 0.99999999999$

Solving (d): Would (c) be unusual

This probability is calculated in (c) above.

$P(atleast\ one) = 0.99999999999$

Because it approximates to 1, we can conclude that it is not unusual

answer: segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

details/explanation:

brown v. board of education of topeka, decided by the us supreme court in 1954, ruled that all americans are entitled to the same civil liberties and protections in regard to access to education. until that decision, it was legal to segregate schools according to race, so that black students could not attend the same schools as white students. an older supreme court decision, plessy v. ferguson (1896), had said that separate, segregated public facilities were acceptable as long as the facilities offered were equal in quality. in the case of brown v. board of education, that standard was challenged and defeated. segregation was shown to create inequality, and the supreme court unanimously ruled segregation to be unconstitutional.

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to education. this was being violated by states whose laws supported the segregation of schools. section 1 of the 14th amendment reads as follows:

all persons born or naturalized in the united states and subject to the jurisdiction thereof, are citizens of the united states and of the state wherein they reside. no state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the united states; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
