Probability Math Puzzles

Lolu hlelo lokusebenza luhlinzeka ngamaphazili ezibalo angaphezu kuka-90 emazingeni amathathu, ukusuka kwabaqalayo kuye kwabaphambili. Izindida zesingeniso ziqondile kodwa ezinye izindida zizoba yinselelo enkulu, ngisho nakubantu abafunde amathuba eleveli yasekolishi -- zama ukuwaphendula wonke! Uma ubhajwa, kukhona iseluleko ngaphansi kwekhasi ngalinye, futhi ungakwazi ukweqa kalula izindida (bese ubuyela kuzo kamuva) ngokuswayipha ubheke phezulu. Kujabulele!

Lolu hlelo lokusebenza luwumkhuba omuhle wezingxoxo zobuningi (okuhlanganisa inani, ezezimali kanye nezingxoxo zobuchwepheshe), zamakilasi amathuba ekolishi, noma kunoma ubani onentshisekelo kuzindida zezibalo.

Ngifake umhlahleli wezibalo ukuze uthayiphe izibalo njengezimpendulo: uma impendulo ithi 0.49^2, isibonelo, ungathayipha okuthi 0.49^2 noma 0.49*0.49 ngaphandle kokuthi uzibekele ukuphindaphinda. Jabulela!
