Odds Verification

Can someone please check my math and please correct me if I am wrong on any of the following odds.
1. Assume Pocket pair, Odds that flop set =.1175501 or 1 in 11
2. Assume flop set, odds the board pairs =.3339502 or 1 in 3
3. Assume flop open ended straight draw, odds of making straight =.3145237 or just less than 1 in 3
4 Assume flop a four flush, odds of making flush =.3524148 or just better that 1 in 3.
5. Odds of going runner runner flush.=.041628 or 1 in 24.

Thanx

<font color="red">1) PP -> Set:

P = 1 - [(48/50)*(47/49)*(46/48)] = .11755 (1/8.5 or 7.5:1)</font color>

2) Set -> Paired board:

P = 1 - [(40/47)*(36/46)] = .33395 (1/3 or 2:1)

3) Open Str8 -> Str8:

P = 1 - [(39/47)*(38/46)] = .3145 (1/3.18 or 2.18:1)

4) Four-Flush -> Flush

P = 1 - [(38/47)*(37/46)] = .3497 (1/2.86 or 1.86:1)

5) Three-Flush -> Flush

P = (10/47)*(9/46) = .041628 (1/24 or 23:1)

....yep, all look good except for #1. You have it right in decimal form but then you wrote 1/11, which is a mistake (probably accidental on your part, since the others are correct).
