Suppose that a 10-Mbps wireless station is transmitting 50-byte frames one immediately after the other.

Andre45 [30]

8 bits = 1 byte

10 Mbps = 10/8 M bytes per second

1 frame = 50 bytes

Frame rate = 10 M / (8 x 50) = 10 M / 400 = 25,000 frames per second

========================

If each frame has an error probability of 0.004, then (0.004 x 25,000) = 100 frames per second are damaged.

1 hour = 3,600 seconds.

100 damaged frames per second = (100 x 3,600) = 360,000 damaged frames per hour.

The Couplet and Limerick classes should also be extended from Poem class. Also, in display method, you call getTitle(), however, it's written as getPoemName() in the Poem class. You need to change the name.
