Alien math?

Question

58% of the population believes the government is suppressing information related to a crashed alien spacecraft in Roswell NM.

36% believes extraterrestrial aliens have never visited Earth.

18% believes aliens have visited Earth, but the Roswell incident does not involve a crashed alien spacecraft. .


What percent of the population believes the Roswell NM incident involves alien life forms that they do not believe exist?

Answer 1

Writing down what is known here.

Let A be the event that the government is surpressing information related to Roswell.

Let B be the event that aliens have never visted Earth. Then

P(A) = 0.58
P(B) = 0.36
P(A' n B') = 0.18 (A' is the complement of A. The way you have this one written does not lead me to believe that this probability is conditional.)

You are looking for P(A n B)

Using DeMorgan's Law, which in part states that A' n B' =
(A u B)',

P(A' n B') = 1 - P(A u B)

So 0.18 = 1 - P(A u B)

P(A u B) = 0.82.

Then using the General Addition Rule for probabilities

P(A u B) = P(A) + P(B) - P(A n B)

0.82 = 0.58 + 0.36 - P(A n B)

0.82 = 0.94 - P(A n B)

P(A n B) = 0.12

So 12% of people believes that Roswell NM incident involves alien life form that they do not believe exist.

You get the same thing if you find P(A' u B') by using

P(A' u B') = P(A') + P(B') - P(A' n B')

and then applying the other part of DeMorgan's Law (A' u B' = {A n B}').

Just curious, are these numbers real or did you make them up?

Answer 3

arithmetic is arithmetic. That mentioned, our arithmetic is base-10 because of the fact we've 10 palms and 10 ft. An alien's mathematical equipment would desire to no longer be in base-10 (because they does no longer inevitably have 10 digits). an trouble-free physique of reference would be top numbers, because they do no longer seem to be divisible by using the different quantity, they're referable by using any base.

Well 2 out of 3 I asked believe that too. I was flabbergasted!
