Answer:

0.7755

Step-by-step explanation:

If 120 CDs are defective, the number of non-defective CDs in the batch is:

$n=1950-120\\n=1830$

In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:

$P=\frac{1830}{1950}*\frac{1829}{1949} *\frac{1828}{1948} *\frac{1827}{1947}\\P=0.7755$

The probability that the entire batch will be accepted is 0.7755.

This problem can be solved directly by neglecting the initial velocity given. All we have to do is to plug in t = 4 in the given equation. That is:

h = -16^2 + 123 * 4

h = 236 ft
