Kifaa cha Kuhesabu Ukubwa
Changanya mambo mawili ya hakika: na, ama, la.
Matokeo yanakuwa bora zaidi unapochapa.
Kuhusu kifaa hiki cha kupigia hesabu
This 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.
The rules it applies are the standard ones for independent events: 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).
Worked example: with P(A) = 50% and P(B) = 30%, both happen with probability 0.5 × 0.3 = 15%, at least one happens with probability 0.5 + 0.3 − 0.15 = 65%, and neither happens with probability 0.5 × 0.7 = 35%. These four outcomes always add up to 100%.
Maswali yaliyoulizwa mara nyingi
Ninapataje uwezekano wa matukio mawili kutukia?
For independent events, multiply their probabilities: P(A and B) = P(A) · P(B). A 50% event and a 30% event both occurring is 0.5 × 0.3 = 0.15, or 15%.
Uhuru unamaanisha nini hapa?
Independent means the outcome of one event has no effect on the other — like two separate coin flips. If the events influence each other (are dependent), these formulas do not apply and you need conditional probabilities.
"A au B" inahesabiwaje?
PKANA au B) = PERA) + P faida) ❖ P faida na B. Kuingilia kati huzuia matokeo ya ushirikiano yasihesabiwe mara mbili, kwa hiyo matokeo hayapiti asilimia 100 kamwe.
Ninapataje uwezekano wa kwamba hakuna tukio lolote linalotukia?
Multiply the chances of each event not happening: P(neither) = (1 − P(A)) × (1 − P(B)). For a 50% and a 30% event that is 0.5 × 0.7 = 0.35, or 35%.
Kuna tofauti gani kati ya "A au B" na "mmoja wao tu"?
"A au B" inajumuisha kisa kinachotokea, wakati "ni moja tu" inayokitenga. " Mmoja tu" ni PKANA au B) kinyume cha PUNA na PALAA na B, akihesabu matokeo mawili ya pekee lakini si yale ya kupishana.
Namna gani ikiwa matukio hayo mawili hayategemei mambo hayo?
Kama tukio moja linaathiri ule mwingine unahitaji uwezekano wenye masharti, P faida na B) = PKSA) PERA) مB | A, na kipima - hesabu hiki kitazidi hali au kitaondoa uwezekano wa kuwa pamoja.
Je, mahabusu haya yanaweza kuongeza zaidi ya asilimia 100?
Matukio manne ya pekee bustani hizo mbili KUNYWA, B pekee, na si É25 tu, sikuzote hujumlika kuwa asilimia 100 kamili. tarakimu kama "A au B" zinaweza kuwa kubwa, lakini hazizidi asilimia 100 kwa sababu upishaji huo unaondolewa.
API bustanini hutumia kifaa hiki cha hesabu kutoka kwenye mfumo wa sheria
Ipigie simu kifaa hiki cha kupigia hesabu kama Junse É not doot toder. Chochote unachoacha kinatumia kiwango kilekile cha mwisho ambacho ukurasa huu haujakamilika; parameta isiyojulikana ni 400, si sufuri kimya kamwe. Soma habari kamili za API docs →
