Functions can be used to model real world situations.
<em>(60,10) is a possible solution because the input and output are feasible.</em>
From the question, we understand that:
--- i.e 60 people donated
---- i.e. 10 families received the clothes from the 60 people
This means that 10 families received at least 60 clothes from the 60 people that donated.
The above illustration can happen.
<em>Hence, (60,10) is a possible solution.</em>

Other conditions that are important are:
3) n is large
4) p is close to 1/2 or 0.5
Step-by-step explanation:
1) Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
2) Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
In order to apply the normal apprximation we need to satisfy these two conditions:
1)
2)
Other conditions that are important are:
3) n is large
4) p is close to 1/2 or 0.5
