Ku saabsan Kalkaaliyahan

example, if the probability of two independent events A and B is 50%, then the probability of both events happening is 100%. The probability calculator takes the chance of two independent events A and B and works out the key combined probabilities: both happening (A and B), at least one happening (A or B), only one of them, and neither happening. It assumes the events are independent, meaning one occurring does not change the chance of the other. Enter each probability as a percentage between 0 and 100.

Su'aalaha badanaa la isweydiiyo

Sideen u heli karaa in ay suurtogal tahay in laba dhacdo oo labadaba ka dhaca?

Maalinta dhacdooyinka madaxbannaan, ku kordhi karaan suurtogalnimada: P (A iyo B) = P (A) · P (B). A 50% dhacdo iyo 30% dhacdo labadaba ka dhaca waa 0.5 × 0.3 = 0.15, ama 15%.

Maxaa madaxbannaan yahay halkan?

Independent macnaheedu waa in natiijada dhacdo mid ka mid ah wax saameyn ah ku yeelan doonaa kale - sida laba kala duwan oo lacag ah flips. Haddii dhacdooyinka saameynta midba midka kale (ay ku xiran yihiin), formulas kuwaasi ma aha in la isticmaalo oo aad u baahan tahay in ay u badan tahay xaaladda.

Sidee loo xisaabiyaa "A ama B"?

P (A ama B) = P (A) + P (B) - P (A iyo B). Ka qaadista isku dhafka ka hortagtaa natiijada la wadaago in la xisaabiyo laba jeer, sidaas darteed natiijada ma ka badan tahay 100%.

Sideen u heli karaa in ay suurtogal tahay in waxba dhacdo dhici?

Ku baddal fursadaha dhacdo kasta oo aan dhicin: P (midna) = (1 − P (A)) × (1 − P (B)). 50% iyo 30% dhacdo ah oo ah 0.5 × 0.7 = 0.35, ama 35%.

Maxaa u dhexeeya farqiga u dhexeeya "A ama B" iyo "mid ka mid ah oo kaliya"?

"A ama B" waxaa ka mid ah xaaladda labadaba ka dhacaan, halka "mid kaliya" ka saaraysaa. "Mid kaliya" waa isku mid P (A ama B) ka yar P (A iyo B), tirinta laba ka mid ah natiijada ka mid ah oo kaliya-laakiin ma aha isku dheelitirka.

Maxaa dhacaya haddii labada dhacdo ma aha kuwo madaxbannaan?

Haddii dhacdo mid ka mid ah saamayn kale aad u baahan tahay in ay suurtogalnimada shuruudaha, P (A iyo B) = P (A) × P (B | A), iyo xisaabinta this waxaa overstate ama understate fursadaha isku dhafan.

Ma awoodaan in ay ku daraan in ka badan 100%?

Afarta natiijooyinka isku midka ah ee kala duwan - labadaba, A kaliya, B kaliya iyo midnaba - waligood waxay ku darayaan si sax ah 100%. Xisaabaadka shakhsi ahaaneed sida "A ama B" waxay noqon karaan kuwo waaweyn, laakiin marnaba ma ka badan yihiin 100% sababtoo ah isku dheelitirka waa la soo saaraa.
