Question

Because of her work schedule, Molly Kay plans to take classes at 8:00, 10:00, and 11:00. Five courses that fit her program are offered at 8:00, nine at 10:00, and two at 11:00. How many different schedules are possible for Molly Kay?

Answer 1

Answer: There are 90 different schedules are possible for Molly Kay.

Explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

`^(5)C_1* ^9C_1* ^2C_1\\\\=5* 9* 2\\\\=45* 2\\\\=90`

Hence, there are 90 different schedules are possible for Molly Kay.
