Give the converse, inverse, and contraposition of the implication.
1. If the year 2020 is a leap year, then there has to be 366 days in that year.
 CONVERSE
If there has to be 366 days in that year, then the year 2020 is a leap year.
 INVERSE
If the year 2020 is not a leap year, then it doesn’t have 366 days in that year.
 CONTRAPOSITION
if it doesn’t have 366 days in a year, then the year 2020 is not a leap year.
