P\u0159ehled a syntaxe funkce PROB<\/h2>\n

Funkce PROB je velmi u\u017eite\u010dn\u00e1 v aplikac\u00edch jako Microsoft Excel a Google Sheets, jeliko\u017e umo\u017e\u0148uje vypo\u010d\u00edtat pravd\u011bpodobnost, \u017ee hodnoty z ur\u010dit\u00e9ho rozsahu se nach\u00e1zej\u00ed v dan\u00e9m intervalu. Tato funkce vy\u017eaduje dva z\u00e1kladn\u00ed vstupy: rozsah hodnot a rozsah odpov\u00eddaj\u00edc\u00edch pravd\u011bpodobnost\u00ed t\u011bchto hodnot.<\/p>\n

Syntaxe funkce PROB je n\u00e1sleduj\u00edc\u00ed:<\/p>\n

PROB(x_range, prob_range, lower_limit, [upper_limit])<\/code><\/pre>\n
    \n
  • x_range<\/code> – Rozsah hodnot X.<\/li>\n
  • prob_range<\/code> – Rozsah pravd\u011bpodobnost\u00ed odpov\u00eddaj\u00edc\u00edch hodnot\u00e1m X.<\/li>\n
  • lower_limit<\/code> – Doln\u00ed hranice intervalu, pro kter\u00fd se m\u00e1 pravd\u011bpodobnost spo\u010d\u00edtat.<\/li>\n
  • upper_limit<\/code> (voliteln\u00fd) – Horn\u00ed hranice intervalu. Pokud nen\u00ed zad\u00e1n, funkce vypo\u010d\u00edt\u00e1 pravd\u011bpodobnost, \u017ee hodnoty X jsou rovn\u00e9 lower_limit<\/code>.<\/li>\n<\/ul>\n
