Final answer:
To calculate the number of options available for the whole course selections, multiply the number of options for each course selection. In this case, the student has 3 main course options (excluding the one with shellfish), 3 dessert options, and 1 drink option (Dr. Pepper). So, there are 9 total options available.
Step-by-step explanation:
To calculate the number of options available for your whole course selections, you need to multiply the number of options for each course selection. In this case, you have 3 available main course options (4 options minus the one with shellfish), 3 dessert options, and 1 drink option (since you have already decided to order Dr. Pepper). So, the total number of options for your whole course selections would be 3 (main course options) multiplied by 3 (dessert options) multiplied by 1 (drink option), which equals 9.
