Simplified Calculation (Calculator Performs All 31 Bets):
Since Selection 4 and Selection 5 lost, only combinations involving Sel 1, Sel 2, and Sel 3 will pay out.
1. Singles:
Sel 1: £10 x (1/1 + 1) = £10 x 2 = £20.00
Sel 2: £10 x (2/1 + 1) = £10 x 3 = £30.00
Sel 3: £10 x (1/2 + 1) = £10 x 1.5 = £15.00
(Sel 4 & Sel 5 Singles are lost)
2. Doubles:
(Sel 1 x Sel 2): £10 x ((1/1+1) x (2/1+1)) = £10 x (2 x 3) = £60.00
(Sel 1 x Sel 3): £10 x ((1/1+1) x (1/2+1)) = £10 x (2 x 1.5) = £30.00
(Sel 2 x Sel 3): £10 x ((2/1+1) x (1/2+1)) = £10 x (3 x 1.5) = £45.00
(Other Doubles involving Sel 4 or Sel 5 are lost)
3. Trebles:
(Sel 1 x Sel 2 x Sel 3): £10 x ((1/1+1) x (2/1+1) x (1/2+1)) = £10 x (2 x 3 x 1.5) = £90.00
(Other Trebles involving Sel 4 or Sel 5 are lost)
4. Four-folds: (All lost as only three selections won)
5. Five-fold Accumulator: (Lost as only three selections won)
Total Stake: £310.00
Total Return: £20.00 + £30.00 + £15.00 + £60.00 + £30.00 + £45.00 + £90.00 = £290.00
Total Profit: £290.00 - £310.00 = -£20.00 (a loss, but significantly less than losing the full £310, demonstrating the bet's inherent safety net)
