Expect in average 10-30 tries for each ship, more or less depending how your luck is. Recipe is important too, each ship has one recipe which gives more % of getting it, such as 4/6/7/2/20 Bismarck (other recipes can still succeed but at a much lower rate, she also requires a German ship as flagship after completing a quest)

Also keep in mind even if you get Yamato now, you will be utterly ruined by her absurd consumption, her alone beats 2 other BBs+ other light ships. LSC isn't the only price to pay for getting her.

Yamato rates

That site has many recipes and their rates, this is the page for Yamato, you can check other ships, but you better learn to recognize their kanji.
