Answer
Precedence order of Boolean operators is following -
not > and > or
True or True and False will evaluate to True
True and True or False will evaluate to True
Work Step by Step
True or True and False can be parenthesized as True or (True and False) because and have higher precedence order than or. (True and False) will become False so our equation will become True or False which will then evaluate to True.
