Answer 2

Number of Different Lunch Options

To calculate the number of different lunch options in the menu, we need to consider the number of choices for each course. According to the information provided, there are 2 options for the first course, 6 options for the second course, and 4 options for the third course.

To find the total number of different lunch options, we multiply the number of choices for each course:

2 (first course) * 6 (second course) * 4 (third course) = 48 different lunch options.

Number of Car License Plate Variants

To calculate the number of car license plate variants for one district, we need to consider the number of available letters and numbers and the restrictions on certain characters.

According to the information provided, the letters "ё," "й," "ь," and "ъ" are not used. Therefore, we can assume that there are 26 letters in the alphabet (excluding these four letters). Additionally, we have 10 digits (0-9) to choose from.

To calculate the number of license plate variants, we need to consider the number of characters in the license plate. Assuming the license plate consists of 3 letters followed by 3 digits, we can calculate the number of variants as follows:

Number of letter variants = 26 * 26 * 26 = 17,576 Number of digit variants = 10 * 10 * 10 = 1,000

Total number of license plate variants = Number of letter variants * Number of digit variants = 17,576 * 1,000 = 17,576,000 license plate variants.

Please note that the calculation assumes a specific format for the license plate and may vary depending on the actual rules and regulations of the district.
