Ndi Mwina chochitika chiyani? Athandizeni ophunzira pokonzekera mayeso

Masamu - imodzi mwa nkhani zovuta kwambiri pa maphunziro a kusukulu. Ndipo onse adzakhala kanthu ngati analibe pochitika mu kalasi la khumi, ndipo ngakhale mu maonekedwe a EGE. Osati zokhazo, mayeso izi zaka zingapo zapitazo anachotsa gawo A, amene anali monga kusankha yankho lolondola kuchokera angapo anapereka, momwemonso Mwina chiphunzitso anawonjezera kuti maphunziro a kusukulu, motero mu mayesero kolowera.

Mwamwayi, mpaka pano, vuto limeneli chimodzi chokha, koma kuthetsa adakali kutero. Childs, ophunzirawo mayeso nkhawa komanso kudziwa mmene kuwerengera Mwina chochitika, kwathunthu achoke mitu yawo. Popewa izi, muyenera bwino kumvetsa zinthu pa siteji ya pokonzekera mayeso.

Ndiye kodi Mwina chochitika? Mu lingaliro ili ndi matanthauzo angapo. Nthawi zambiri ankaona otchedwa "chakale". Mwina wa zosayembekezereka ya chochitika - ndi chiŵerengero chiwerengero cha zotsatira zake zabwino kwa chiwerengero zonse zotheka: P = m / N.

Kuyambira tanthauzo limeneli, katundu zotsatirazi:

1. Ngati chochitika ndi ena, Mwina wa mgwirizano. Pankhaniyi, zomwe zakambidwa zonse zidzakhala bwino.

2. Ngati chochitikacho sizotheka, ndiye Mwina ake ndi ziro. Pankhaniyi amakhala ndi pakalibe zakambidwa yabwino.

3. Mwina ubwino uliwonse tsoka lagona mu osiyanasiyana kuchokera ziro umodzi.

Koma tanthauzo ndi katundu wa kudziwa zambiri sikokwanira kuthetsa ntchito pa nkhaniyi mu Wonse State mayeso. Mwina chochitika ndi zina zofunika kuchita masamu ndi Kuwonjezera ndi chulutsa theorems. Ndi mmodzi uti ntchito zimadalira zikhalidwe za vutolo. Chirichonse pano ndi pang'ono zovuta, koma ngati mukufuna ndi khama kuphunzira zinthu zimenezi.

Ngati zochitika ziwiri sangathe onse chifukwa cha mayeso amodzi, ndiye iwo amatchedwa atakwatirana. Mwina awo kuchita masamu ndi Kuwonjezera Lingaliro Lovomerezeka:

P (A + B) = P (A) + P (B), kumene A ndi B - zochitika atakwatirana.

Mwina zochitika palokha kuchita masamu kuti tinachita mfundo chogwirizana aliyense wa iwo (chulutsa Lingaliro Lovomerezeka). Zimenezi zingakhale Mwachitsanzo, polasa pamene kuomba mfuti ziwiri. M'mawu ena, palokha zochitika - anthu zakambidwa amene ali osadalira pa wina ndi mzake.

Ngati zotsatira ndi zogwirizana, ndiye ntchito Mwina makonzedwe. Events amatchedwa yozungulira.

Kuwerengetsa Mwina mmodzi wa iwo, choyamba tiyenera kuganizira zimene ndi mzake. Choncho, poyamba pa zonse, kudziwa zimene chochitika kumabweretsa wina. Ndiye kuwerengetsa Mwina ake. Kungoganiza kuti mwambo umenewu zinachitika, ndi kukula chimodzimodzi kwa wachiwiri. Mwina makonzedwe Pankhaniyi kuchita masamu kuti tinachita nambala yoyamba analandira pa wachiwiri. Ngati zinthu zosiyanasiyana chonchi, njira ndi yovuta, koma ife Zisakhale, chifukwa mayeso si zothandiza kwa ife.

mutu uliwonse mosavuta anaphunzira ngati kudutsa bwino mu nkhani. Mwina chochitika - yotero. Kuti athetse mavuto a nthambi ili la masamu, tiyenera athe kuganiza mwanzeru ndiponso kudziwa matanthauzo zogwirizana ndi kachitidwe tafotokozazi. Ndiye palibe mayeso inu si mantha!
