Using the binomial distribution, it is found that there is a 0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, for the parameters, we consider that:
- 10% of the 9-year old children in a town have three siblings, hence p = 0.1.
- Fifteen 9-year old children are selected at random, hence n = 15.
The probability that more than 3 of these selected children have three siblings is given by:

In which:

Then:






P(X > 3) = 1 - 0.9445 = 0.0555
0.0555 = 5.55% probability that more than 3 of these selected children have three siblings.

h + h + 29
This will be simplified into 2h + 29
The shorter tree's height is represented with the variable 'h'
Because the taller tree is 29 feet taller, the equation for the taller tree would be 'h + 29'
SInce we're looking for the sum, all you have to do is add 'h' and 'h + 29'
