Umzekelo: ukubheja kwicandelo
“Ishumi elinesixhenxe nabamelwane”, iitshiphu ezintlanu ngexesha, kangangeyure. Indlela iseshoni yecandelo levili eziva ngayo nexabiso layo.
Iseshoni elinganisiweyo yemijikelo engama-50 yeetshiphu ezintlanu ze-$2 ku-2-25-17-34-6, umphetho wezikhewu ezintlanu ojikeleze u-17. Ukubetha okusixhenxe kwimijikelo engama-50, inzuzo yokwenyani +$4 emva kokuhla nge-$120. Iibheji zenani elinye ezintlanu ezinebali, kwaye ibali alitshintshi nto.

Kutheni icandelo
Kuba ingumphetho wenene wevili, obalulekileyo ukuba kwaye kuphela ukuba ivili lithambekele kuloo mphetho, kwaye asinabungqina boko. Ngaphandle kokuthambekela, ibheji yecandelo ziibheji zenani elinyeibhejiInani elinyeInani elinye, ihlawula u-35:1.Funda yonke → ezintlanu ezingadibananga: inzuzo yekhasino efanayo, intlawuloimaliIntlawuloOko ibheji ephumeleleyo ikubuyisayo, okuxelwa njengo-“X ku-1” ngaphezulu kwebheji ebuyisiweyo.Funda yonke → efanayo, ii-odds ezifanayo no-2, 25, 17, 34 no-6 ezikhethwe ngenxa yokuba yayiyimihla yokuzalwa yomntu othile. I-racetrack yenza kube lula ukuyibeka kwaye inika ingokuhlwa ibali. Izibalo azifundi mabali.
Oko umdlali wokuthambekela ebeya kukwenza ngokwahlukileyo
Ngewayeqale warekhoda amawaka emijikelo kweli vili lithile, wafumana icandelo elibetha ngaphezu kwe-5/37 kwiisampuli ezimbini ezimeleyo, waza walibheja ngebheji elungelelaniswe nenzuzo elinganisiweyo. Ukubetha kwethu okusixhenxe kwimijikelo engamashumi amahlanu akubobungqina bento; iphepha elithi Ubungakanani besampulu kwiLebhu lithi besiya kudinga imijikelo ephindwe kalikhulu ukuze sithi ingaba lo mphetho ushushu na. Siyibhejile kuba u-17 linani elihle, nto leyo isisizathu esifanayo nesabo bonke.
Imibuzo
Ziyafana ngaphandle kokuba ivili lithambekele kuloo mphetho, nto ethatha amawaka emijikelo ukuyazi.
Itafile ye-$10 nebheji ebizwayoitafileIbheji ebizwayoIbheji ebhengezwa kumqhubi endaweni yokubekwa ngesandla, ngokwesiqhelo ibheji yecandelo levili efana ne-voisins okanye i-tiers. Kwakhona “ibheji ebhengeziweyo”.Funda yonke → yeetshiphu ezintlanu. Ubuncinci bebheji yangaphakathi busebenza kwisimbuku.
“Ngo-3” kubeka iitshiphu ezisixhenxe ezigubungela izikhewu ezisixhenxe kwi-18.9%. Inzuzo yekhasino efanayo, uhambo olugudileyo.
Uncumo
Iibheji zenani elinye ezintlanu ezinebali. Ivili alifundi.
