hi guys. im here again, and facing one of the most difficult question ever faced before. so hope u can help me. below is the question and how im thinking.(adsbygoogle = window.adsbygoogle || []).push({});

Someone would label the two competing soccer teams as the Red Team and the Green Team. An unknown number of red ping-pong balls, green ping-pong balls, and white ping-pong balls would be put inside a black bag. She would pick up 5 balls randomly from this bag for every minute that the soccer match is in play, and return all 5 balls back into the bag. If she had picked ALL red balls, she would cause a Red Team player to score a goal within that minute. If she picked ALL green balls, she would cause a Green Team player to score a goal within that minute. If she picked ALL white balls, she would cause the soccer match to be abandoned. THE QUESTION ASK ABT THE PROBABILITIES AS NORMAL. [e.g What is the probability that the Red Team will score a goal in any one minute?]

BUT THE PROBLEM IS I DUN KNOW THE TOTAL NUMBER OF THE BALLS, AND WHETHER THE NUMBER OF RED BALLS AND WHITE BALLS AND GREEN BALLS ARE EQUAL. and TO FIND OUT THE TOTAL NUMBER OF BALLS, DO I HAVE TO USE X AND Y , INSTEAD OF ORDINARY WAY OF CALCULATION, AND I HAVE TO USE ASSUMPTION TO SOLVE THE PROBLEM RIGHT? is there permutation and combination involved?

THANKS..
