Qhov yuav tshwm sim = tus naj npawb ntawm txoj kev ua tiav. tag nrho cov txiaj ntsig tau. Rau piv txwv , cov qhov tshwm sim ntawm flipping ib npib thiab nws ua taub hau yog ½, vim hais tias muaj 1 txoj kev tau ib lub taub hau thiab tag nrho cov uas tau tshwm sim yog 2 (lub taub hau los yog tus Tsov tus tw).
Tsis tas li ntawd, qhov tshwm sim piav qhia nrog ib qho piv txwv yog dab tsi?
Qhov yuav tshwm sim . Qhov yuav tshwm sim yog qhov yuav tshwm sim uas yuav tshwm sim thiab suav los ntawm kev faib cov txiaj ntsig zoo los ntawm tag nrho cov txiaj ntsig tau tshwm sim. Qhov yooj yim tshaj plaws piv txwv yog npib npib. Muaj 50% txoj hauv kev uas qhov tshwm sim yuav yog taub hau, thiab muaj 50% txoj hauv kev uas qhov tshwm sim yuav yog tails.
Tom qab ntawd, lo lus nug yog, qhov tshwm sim piav qhia yog dab tsi? Qhov yuav tshwm sim yog ib ceg ntawm kev ua lej uas cuam tshuam nrog kev suav qhov yuav tshwm sim ntawm qhov tshwm sim, uas tau qhia tias yog tus lej ntawm 1 thiab 0. Txhua lub npib tos yog qhov kev tshwm sim ywj pheej; qhov tshwm sim ntawm ib qho kev sim tsis muaj kev cuam tshuam rau cov tom ntej.
Ib tug kuj yuav nug, dab tsi yog ib co piv txwv ntawm lub neej tiag tiag ntawm qhov tshwm sim?
8 Cov Piv Txwv Lub Neej Muaj Peev Xwm
- Huab Cua Huab Cua. Ua ntej npaj rau kev tawm mus ncig lossis noj mov, peb ib txwm saib xyuas huab cua huab cua.
- Batting Nruab Nrab hauv Cricket.
- Kev nom kev tswv.
- Flipping ib npib los yog tsuav.
- Kev pov hwm.
- Puas yog peb yuav tuag hauv kev sib tsoo?
- Daim pib rho npe.
- Daim npav ua si.
3 hom kev tshwm sim yog dab tsi?
Peb Hom Kev Ua Tau Zoo
- Classical: (qhov tshwm sim sib npaug sib npaug) Cia S = qhov chaw piv txwv (teem ntawm txhua qhov tshwm sim sib txawv).
- Relative Frequency txhais.
- Subjective Probability.

Yam ua piv txwv piv txwv li cas?
Ib khub xaj yog ib khub ntawm tus lej hauv ib qho kev txiav txim. Piv txwv li, (1, 2) thiab (- 4, 12) raug txiav ua khub. Qhov kev txiav txim ntawm ob tus lej tseem ceeb: (1, 2) tsis sib npaug rau (2, 1) -- (1, 2) ≠ (2, 1)
Dab tsi yog qhov sib piv thiab piv txwv?
Inverse proportion. Inverse proportions tshwm sim thaum ib tus nqi nce thiab qhov txo qis. Piv txwv li, ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
