In some popular variations of poker, a player uses the best five-card poker hand out of seven cards. The frequencies are calculated in a manner similar to that shown for 5-card hands, except additional complications arise due to the extra two cards in the 7-card poker hand. The total number of distinct 7-card hands is . It is notable that the probability of a no-pair hand is less than the probability of a one-pair or two-pair hand.

The royal flush is not included in the cumulative probability calculation because it is a type of straight flush. The Ace-high straight flush or royal flush is slightly more frequent (4324) than the lower straight flushes (4140 each) because the remaining two cards can have any value; a King-high straight flush, for example, cannot have the Ace of its suit in the hand (as that would make it ace-high instead).

Hand	Frequency	Probability	Cumulative	Odds
Royal flush	4,324	0.0032%	0.0032%	30,939 : 1
Straight flush	37,260	0.0279%	0.0311%	3,216 : 1
Four of a kind	224,848	0.168%	0.199%	594 : 1

Straight	6,180,020	4.62%	10.4%	20.6 : 1
Three of a kind	6,461,620	4.83%	15.3%	19.7 : 1

Since suits have no relative value in poker, two hands can be considered identical if one hand can be transformed into the other by swapping suits. Eliminating identical hands that ignore relative suit values leaves 6,009,159 distinct 7-card hands.

The number of distinct 5-card poker hands that are possible from 7 cards is 4,824. Perhaps surprisingly, this is fewer than the number of 5-card poker hands from 5 cards because some 5-card hands are impossible with 7 cards (e.g. 7-high).

2. Frequency of 7-card lowball poker hands

In some variants of poker a player uses the best five-card low hand selected from seven cards. In most variants of lowball, the ace is counted as the lowest card and straights and flushes don't count against a low hand, so the lowest hand is the five-high hand A-2-3-4-5, also called a wheel. The probability is calculated based on , the total number of 7-card combinations.

The table does not extend to include five-card hands with at least one pair. Its "Total" represents 95.4% of the time that a player can select a 5-card low hand without any pair.

Hand	Frequency	Probability	Cumulative	Odds
5-high	781,824	0.584%	0.584%	170.12 : 1
6-high	3,151,360	2.36%	2.94%	41.45 : 1
7-high	7,426,560	5.55%	8.49%	17.01 : 1
8-high	13,171,200	9.85%	18.3%	9.16 : 1
9-high	19,174,400	14.3%	32.7%	5.98 : 1
10-high	23,675,904	17.7%	50.4%	4.65 : 1
Jack-high	24,837,120	18.6%	68.9%	4.39 : 1
Queen-high	21,457,920	16.0%	85.0%	5.23 : 1
King-high	13,939,200	10.4%	95.4%	8.60 : 1
Total	127,615,488	95.4%	95.4%	0.05 : 1

If aces are not low, simply rotate the hand descriptions so that 6-high replaces 5-high for the best hand and ace-high replaces king-high as the worst hand.

처음은 1995년 8월 5일, 우리나라 최초 상업 위성인 무궁화 1호를 발사하던 Delta II는 추진체 9개중 한개가 분리가 안되어서 정상 궤도에 위성을 진입시키지 못하여 위성 자체의 연료를 소모시시켜 정상 궤도로 진입을 하였다. 그 결과 10년 예상이던 위성 수명이 5년 이내로 줄어들었다.

두번째 실패는 1997년 1월 17일에 있던 GPS위성을 발사하던 도중, 발사 직후 13초 후에 공중에서 폭발하여 발사장 부근에 수많은 불타는 파편을 뿌리는 사고가 있었다. 다행이도 인명사고는 없었으며 발사장도 피해가 크지 않았다고 한다.

위 동영상은 이 두번째 사고의 동영상이며 굉장히 화려함을 알 수 있다. 물론 사고이지만 인명사고는 없었다고 하니 그냥 화면을 즐겨도 될 듯하다.
