Din 1000 bilete la un joc, puse în vânzare într-o săptămână, 10 bilete sunt câștigătoare. La o agenție se repartizează la întâmplare 100 bilete. Care este probabilitatea ca 3 bilete dintre cele repartizate să fie câștigătoare?

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

250c+180g≥950
