So, the count went down from 850 to 500, or 350 units.
if we take the 850 to be the 100%, what is 350 in percentage off of it?
solve for "x".

Answer:
0.1426 = 14.26% probability that at least one of the births results in a defect.
Step-by-step explanation:
For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability that a birth results in a defect is independent of any other birth. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).
This means that
A local hospital randomly selects five births.
This means that
What is the probability that at least one of the births results in a defect?
This is:
In which
0.1426 = 14.26% probability that at least one of the births results in a defect.
