In the example 2 sir, how can we derive at least 15 strings from it?

4:40 what if there is another string that generated from this grammar and is ambiguity will the grammar be ambiguity or not :)?

[@sagarbadhiye]

if any particular string is derivable in two ways(two parse tree) for a given grammar, then the grammar is ambiguous
