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 uses the following rules: P(A and B) = P(A) × P(B); P(A or B) = P(A) + P(B) − P(A and B); P(neither) = (1 − P(A)) × (1 − P(B)); and "only A" is P(A) − P(A and B). A pie chart splits the sample space into the four mutually exclusive outcomes (both, A only, B only, neither).The probability calculator uses the following rules: P(A and B) = P(A) × P(B); P(A or B) = P(A) × P(B); P(neither) = P(A) × P(B) × (1 − P(A)). The probability calculator uses the following rules: P(A) = P(A) × P(B); P(B) = P(A) × P(B); P(B) = P(A) × P(B); P(A) = P(B) × P(B). The probability calculator uses the following rules: P(A) = P(A) × P(B); P(B) = P(A) × P(B); P(B) = P(A) × P(B); P(B) = P(B) × P(B); P(A) = P(B) × P(B); P(B) = P(A) × P(B); P(B) = P(B) × P(B); P(A) = P(B) × P(B); P(B) = P(B) × P(B); P(B) = P(B) × P(B); P(B) = P(A) × P(B); P(B) = P(A) × P(B); P(B) = P(B) × P(B); P(A) = P(
Mafunso ofunsidwa nthawi zambiri
Kodi ndingapeze kuthekera kwa zifukwa ziwiri onse kuchitika?
Kwa zochitika zosagwirizana, kuwonjezeka kwa zotheka zawo: P (A ndi B) = P (A) · P (B). 50% chitsanzo ndi 30% chitsanzo onse kuchitika ndi 0.5 × 0.3 = 0.15, kapena 15%.
Kodi ndi chiyani chimene chimatanthauza kuti ndi wodziyimira pawokha?
Independent amatanthauza kuti zotsatira za chikondwerero chimodzi alibe zotsatira pa ena - monga awiri osiyana coin flips. Ngati zikondwerero kukhudzana wina ndi mzake (ndi otengera), izi formulas sayenera kuchitidwa ndi inu muyenera conditional zotheka.
Kodi "A kapena B" imawerengedwa bwanji?
P (A kapena B) = P (A) + P (B) - P (A ndi B).Kuchotsa kukhudzana kumaletsa zotsatira zogawana kuti ziwerengedwe kachiwiri, kotero zotsatira sizimapitilira 100%.
Kodi ndingapeze mwayi kuti palibe nkhaniyi chimachitika?
Kuwonjezera mwayi wa chilichonse nkhaniyi sichichitika: P (osati) = (1 - P (A)) × (1 - P (B)). kwa 50% ndi 30% nkhaniyi kuti ndi 0.5 × 0.7 = 0.35, kapena 35%.
Kodi pali kusiyana kotani pakati pa "A kapena B" ndi "mmodzi mwa iwo"?
"A kapena B" amaphatikizapo milandu yomwe imakhalapo, pomwe "mmodzi yekha" imachotsa. "Mmodzi yekha" ndi P (A kapena B) minus P (A ndi B), kuwerengetsa zotsatira ziwiri zokha-zokha koma sizogwirizana.
Kodi ngati zifukwa ziwirizi sizili zosiyana?
Ngati msonkhano wina amakhudza ena muyenera conditional kuthekera, P (A ndi B) = P (A) × P (B | A), ndi izi calculator adzamva kapena kukana kugwirizana mwayi.
Kodi izi zikhoza kuwonjezera mpaka kuposa 100%?
Masiku ano, anthu ambiri amagwiritsa ntchito njira yoti awerenge kuchuluka kwa zinthu zomwe zili m'mabuku a m'Baibulo. Mafunso awiriwa amatanthauza kuti anthu akhoza kufunsa mafunso angapo, koma nthawi zonse amapeza yankho limodzi.
