Cov txheej txheem ntawm tag nrho cov txiaj ntsig tau raug hu ua qhov chaw piv txwv ntawm qhov kev sim thiab feem ntau yog qhia los ntawm S. Ib qho subset E ntawm qhov chaw qauv S yog hu ua ib qho kev tshwm sim. Nov yog qee qhov piv txwv. Piv txwv 1 Tossing ib npib.
Hais txog qhov no, piv txwv li qhov chaw piv txwv yog dab tsi?
Cov qauv qhov chaw ntawm qhov kev sim yog tag nrho cov txiaj ntsig tau rau qhov kev sim ntawd. Ob peb yam yooj yim piv txwv : Cov qhov chaw rau pov ib npib: {Head, tails.} The qhov chaw Rau qhov pov ntawm qhov tuag: {1, 2, 3, 4, 5, 6.}
Tsis tas li ntawd, qhov txawv ntawm qhov xwm txheej thiab qhov chaw piv txwv yog dab tsi? Nws yog qee zaum tsis meej pem nrog qauv qhov chaw ntawm ib qho kev sim, xa mus rau feem ntau los ntawm omega (Ω), tab sis yog txawv :thaum qauv qhov chaw ntawm qhov kev sim muaj tag nrho cov txiaj ntsig tau, qhov qhov chaw tshwm sim muaj tag nrho cov kev tshwm sim; tag nrho cov subsets qauv qhov chaw.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov ntsiab lus ntawm qhov chaw piv txwv?
Nyob rau hauv cov ntaub ntawv ntawm ib tug toss, lub qauv qhov chaw muaj ob cov ntsiab lus uas interchangeably, tej zaum yuav denoted li, hais, {Lub taub hau, Tail}, los yog {H, T}, los yog {0, 1}, Muaj rau qhov tshwm sim tau thiab cov qauv qhov chaw muaj rau cov ntsiab lus : {1, 2, 3, 4, 5, 6}.
Yuav ua li cas koj xam qhov chaw seem?
Siv cov qauv P = Cov xwm txheej tshwj xeeb / Sample Space , peb ua tau xam tus qauv qhov chaw yog tias peb tau txais qhov tseem ceeb (lossis muaj peev xwm ua tau) qhov tshwm sim thiab qhov xwm txheej tshwj xeeb.

Dab tsi yog qhov sib txawv ntawm cov xwm txheej tag nrho thiab qhov chaw coj mus kuaj?
Qhov chaw piv txwv ntawm kev sim yog cov txheej txheem ntawm txhua qhov ua tau. Yog tias qhov kev sim pov tseg tuag, qhov chaw piv txwv yog {1, 2, 3, 4, 5, 6}. Exhaustive Txheej xwm. Ib lossis ntau qhov xwm txheej tau hais kom tag nrho thaum lawv zoo li qhov tsawg kawg yog ib qho ntawm cov xwm txheej tau tshwm sim
Dab tsi yog qhov txawv ntawm qhov chaw thiab qhov chaw?
Raws li lub npe qhov txawv ntawm qhov chaw thiab qhov chaw yog qhov chaw yog (tso tseg) kev tu siab, kev tu siab orsite tuaj yeem yog qhov chaw uas txhua yam raug kho; qhov xwm txheej; txoj hauj lwm hauv zos; xws li, qhov chaw ntawm lub nroog los yog ntawm ahouse thaum qhov chaw yog ib qho chaw tshwj xeeb lossis qhov chaw nyob hauv lub cev
Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Lub organelle twg ua haujlwm raws li qhov chaw xa ntawv ntawm lub xov tooj ntawm tes txheeb cov proteins thiab xa lawv mus rau lawv qhov chaw xav tau sab hauv lossis sab nraud ntawm tes?
Golgi Hais txog qhov no, dab tsi organelle yog lub luag haujlwm rau kev thauj mus los? endoplasmic reticulum (ER Qhov thib ob, cov proteins txav mus los ntawm lub cell li cas? Cov proteins txav mus los endomembrane system thiab raug xa tawm los ntawm lub ntsej muag trans ntawm Golgi apparatus nyob rau hauv thauj vesicles uas txav mus los cytoplasm thiab tom qab ntawd fuse nrog plasma membrane tso tawm protein ntau mus rau sab nraum lub cell .
Lub npe ntawm cov enzyme uas kuaj pom hauv qhov kev kuaj pom zoo catalase yog dab tsi?
Catalase Test- Ntsiab Cai, Siv, Txheej Txheem, Txhais Lus Txhais nrog ceev faj. Qhov kev sim no qhia pom tias muaj catalase, ib qho enzyme uas ua rau cov pa tawm ntawm cov pa oxygen los ntawm hydrogen peroxide (H2O2)
