Calculating Outs - 撲克牌

不好意思 我想請教一下大家關於outs的問題

我看書上面寫的 看不太懂

手牌是 Qs 10s

flop是 As Jh 8c

所以K 9出來會變成straight 所以straight有 8 outs

也有可能turn and river出來都是spade 這樣就變成flush

書上面寫說

The chance of the spade on the turn(other than the K spade and
the 9 spade, which were already counted as straight cards) is 8/47.
The chance of following that with a spade on the river is then 7/46
A quick way of looking at this is eight outs on the turn, but only
about 1/6 of those make a flush on the river. That's a total of
about 2 more outs

那個我不太懂1/6是怎麼來的 是8/47 or 7/46大約是1/6嗎？

還有flush會有兩個outs我也不太懂

麻煩請知道的人 解釋一下 謝謝你囉
