Substitute:

C(69,5) = 69! ÷ (5! × (69-5)!)
C(5,0) = 5! ÷ (0! × (5-0)!)
C(69-5,5-0) = 64! ÷ (5! × (64-5)!)
C(26,1) = 26! ÷ (1! × (26-1)!)
C(1,1) = 1! ÷ (1! × (1-1)!)
C(26-1,1-1) = 25! ÷ (0! × (25-0)!)
! means 'Factorial' eg: 69! = 69 × 68 × 67 ... × 1

Simplify:
69! ÷ (5! × (69-5)!) = 11,238,513
5! ÷ (0! × (5-0)!) = 1
64! ÷ (5! × (64-5)!) = 7,624,512
26! ÷ (1! × (26-1)!) = 26
1! ÷ (1! × (1-1)!) = 1
25! ÷ (0! × (25-0)!) = 1
292,201,338 = 38
7,624,512
Calculate:
(11,238,513 ÷ 7,624,512) × (26 ÷ 1) = 38

Approx. Overall Odds: 1 in 25
