could you walk be through this please?

The first one is convenience sampling because each customer is already "presented" because each is a patient and was available already for other reasons: medical treatment.

The second is stratified sampling because a set percentage is taken from a "separated" 2 groups: stratified into male/female.

The third is volunteer sampling because the customers may or may not answer back.  It would only be at the customer's volition or choosing to respond.

The fourth is systematic sampling because a regimented, selected, interval is used across the board.
