P(over 6 ft) = 8/27
P(good aim) = 7/27
P(over 6 ft of good aim) = 8/27 + 7/27 = 15/27 = 5/9
6 sec can take penny to strike the ground.

Re-arrange the terms from greatest degree to smallest degree.

We can solve it by applying quadratic formula,

Here a = –16, b = 48, c = 288




Now, write find two t's using plus and minus operation.


t = –3 (or) t = 6
We cannot write time is negative. so neglect t = –3.
Therefore t = 6.
Hence 6 sec can take penny to strike the ground.
