Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:

To break this down, we have:


By solving the equation:

Answer:
3 seconds
Step-by-step explanation:
Maximum height=150
150=-16t^2+96t+6
-16t^2+96t-144=0
-16(t^2-6t+9)=0
-16(t-3)^2=0
t=3 seconds
