Final answer:
Text message users send or receive an average of 41.5 messages per day. One user sends or receives approximately 1.729 messages per hour. More information is needed to calculate the exact probabilities of receiving or sending two or more messages per hour.
Step-by-step explanation:
To answer this question, we need to consider the average number of text messages sent per day. According to the given information, text message users send or receive an average of 41.5 text messages per day.
a. To find the number of text messages sent per hour, we divide the average number of messages per day by 24 (hours): 41.5 / 24 = 1.729. So, a text message user sends or receives approximately 1.729 messages per hour.
b. To find the probability of receiving or sending two messages per hour, we need to use the average number of messages per hour. In this case, the average would be 1.729. However, we need more information to calculate the exact probability, such as the distribution of message counts per hour.
c. Similarly, to find the probability of receiving or sending more than two messages per hour, we would need additional information about the distribution of message counts per hour.
