Even Odds.
Let E stand for the set of all even natural numbers (so E = {2,4,6,8….} and O stand for the set of odd natural numbers ( O = {1, 3, 5, 7,….}. Show that the sets E and O have the same cardinality by describing an explicit one-to-one correspondence between the two sets.

step-by-step explanation:

80

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
