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 = <em>25,000 frames per second</em>
========================
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) = <em>360,000 damaged frames per hour.</em>
