You play 4 pairs on the ticket and the 3 out of 4 system, this means that you need to hit a minimum of 3 matches for the ticket to be won.
In the 3 out of 4 system there are a total of 4 combinations. We calculate the payment per combination by dividing the total payment on the ticket by the total number of combinations per ticket.
If the total payment on this ticket is 1000 NGN, the payment per combination is 1000/4=250, that is, 250 NGN per winning combination.
Let’s take for example that A, B, C and D represent the matches on the ticket. If three matches were hit, the ticket was won because the minimum requirement was exactly 3 matches. If, for example, matches A, B and D are hit, then we have one winning combination and that is ABD.
And the odds are 1.90
B odds 1.95
C odds 2.00
D odds 1.80
(A 1.90 * B 1.95 * D 1.80)*250 NGN = 1,667.5 NGN is a profit
Below are announced combinations of systems 3 out of 4 with a total payment on the ticket of 1000 NGN, i.e. 250 NGN per combination:
(ABC)* payment per combination 250 NGN (1.901.952.00)250=7.41250=1852.5 NGN
(ABD)* payment per combination 250 NGN (1.901.951.80)250=6.67250=1667.5 NGN
(ACD)* payment per combination 250 NGN (1.902.001.80)250=6.84250=1710 NGN
(BCD)* payment per combination 250 NGN (1.952.001.80)250=7.02250=1755 NGN
If all four games are affected, when we calculate each combination separately, it is necessary to add them together and thus arrive at the payout amount.
1852.5+1667.5+1710+1755=6985 NGN
The total amount paid on the ticket in this case amounts to NGN 6985.
If we play the same 3 out of 4 system with one fix, we increase the winnings, but the condition on the ticket changes. It is necessary that the match in the fix is hit as well as a minimum of 3 matches in the system in order for the ticket to be won.
The profit is calculated by using the winning combination, e.g. (ABD)* payment per combination is multiplied by the quota in the fix and thus we get the payment amount.

Note:
*Minimum payment per combination is Ngn 10.
