a. 45ways b. 3.95years

Step-by-step explanation:

The composer Beethoven wrote 9 symphonies, 5 piano concertos, and 32 piano sonatas

(a) There are 9*5 ways to play first a Beethoven symphony and then a Beethoven piano concerto

9*5=45

(b) The manager of a radio station decides that on each successive evening (7 days per week), a Beethoven piano sonata will be played followed by a Beethoven symphony followed by a Beethoven piano concerto.

there are 32*9*5 combinatios of piano sonata followed by a Beethoven symphony followed by a Beethoven piano concerto.

32*9*5=1440

1440 nights / 365 days = 3.95 years
