Answer:
Step-by-step explanation:
We are given that G be a finite group with have two elements of order two.
We have to prove that <x,y> is either abelian or isomorphic to a dihedral group.
<x,y> means the group generated by two elements of order 2.
We know that is a cyclic group and number of elements of order 2 is always odd in number and generated by one element .So , given group is not isomorphic to
But we are given that two elements of order 2 in given group
Therefore, group G can be or dihedral group
Because the groups generated by two elements of order 2 are and dihedral group.
We know that is abelian group of order 4 and every element of is of order 2 except identity element and generated by 2 elements of order 2 and dihedral group can be also generated by two elements of order 2
Hence, <x,y> is isomorphic to or .
It’s a or b I’m. To really sure
To find the best estimate for the percentage just divide 64/75 and you should get 85.3% and you can round that to 85%.
