Final answer:
Joey got a greater percentage of voicemail messages than Regan.
Step-by-step explanation:
To find out who got a greater percentage of voicemail messages, we need to compare the percentages of voicemail messages received by Joey and Regan.
Let's start with Joey. We know that out of his 3 phone calls, he got a voicemail message on 2 of them. To find the percentage, we divide the number of voicemail messages by the total number of phone calls, and then multiply by 100.
- Percentage of voicemail messages for Joey: (2/3) * 100 = 66.67%
Next, let's calculate the percentage for Regan. We are given that Regan got a voicemail message 65% of the time. So Regan's percentage of voicemail messages is 65%.
Comparing the percentages, we see that Joey got a greater percentage of voicemail messages than Regan. Therefore, the answer is Joey (a).
