Let me explain the calculation in the post you mentioned.
That calculation was... (58x57x56x55x54x53) รท (6x5x4x3x2x1).
It was divided by (6x5x4x3x2x1), because it was assumed there are 6 separate pots. So, the same number (or ball) has 6 possiblity of being drawn.
Why this (flaw) assumption? Because he was thinking of the 6 numbers he selected. The 1st number he selects, has 6 chances (because of 6 draws). The 2nd number, has 5 chances (5 draws remaining), etc. etc.
But in hitting the jackpot, one must match all 6 numbers, so in reality the 1st number you wrote don't have 6 chances, your 2nd number don't have remaining 5 changes of being drawn, etc. etc
So, the probability is still 1 in 29 billion. (Without divided by 6x5x4x3x2x1 times.)
Why are you doing all this calculations? just take rm2 from your wallet and buy lar.... it's just rm2. Buy for fun la diu.... huat ah... kek
