Going through the old ones, I find that the maximum possible number of ways the nine planets may not occupy the 6th, 8th & 12th house, has to be calculated as follows :-
1. Seven Planets (other than Rahu & Ketu) can occupy any place but Rahu and Ketu are always in the opposite house to each other.
2. For the seven Planets (other than Rahu & Ketu) not to occupy the 6th, 8th or 12th house means they can occupy any of the other nine houses, the probability of which is 9 for each planet - meaning - 63 (9 x 7).
3. Now for Rahu & Ketu, their positions if they occupy 6th, 8th or 12th houses, will be like (For Rahu) 6 - 12, 8 - 2 & 12 - 6 or the other way round (For Ketu) 12 - 6, 2 - 8 or 6 - 12 and we see that 6 - 12 & 12 - 6 combinations are repeated twice. So out of total of these six positions, we remove two and we are left with a total of four positions. Thus to calculate the probability of Rahu occupying the other eight houses (Ketu will be automatically taking the opposite house) will be 8 (8 x 1).
4. So the total number of possible combinations for none of the planets to be there in 6th, 8th & 12th houses will be 63 + 8 = 71 [out of a total of 96 (12 x 8) - taking only one set of combinations for Rahu & Ketu]. Private Reply to H.K.L. Sachdeva (new win) |
