Let a, b∈g, where g is a group. then which one of the following statement is not true.
a)if a, b,ab have same order then ab=ba
b)if a^3=e, the identity element of g and aba^-1=b^2 then order of b=16
c)ab and ba have same order
d)b and aba^-1 have same order

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
