Answer-
The inverse of the statement “If I do not buy a ticket, then I do not go to the concert" is "If I buy a ticket, then I go to the concert."
Solution-
In order to form the inverse of any conditional statement, we have to take the negation of both the hypothesis and the conclusion.
In this case, the hypothesis is, "if I do not buy a ticket"
And the the conclusion is, "then I do not go to the concert"
The negation of the hypothesis would be - "if I buy a ticket",
And the negation of the conclusion would be - "then I go to the concert"
Therefore, the inverse of the statement “If I do not buy a ticket, then I do not go to the concert" is "If I buy a ticket, then I go to the concert."
