this is not LL(1) because intersection is there,both are going to same cell infact this grammer is ambiguous.

Ambiguous grammer cannot parse by any parsers except operator precedence parser

If a grammar is ambiguous then it never be LL(1),LR(0),SLR,LALR,CLR.

Given grammar is ambiguous . So its not LL(1)

and if the grammar is ambiguous it can not be LL(1), LR(0),SLR(1), LALR(1) and CLR(1) also.
