The possible values for the missing number that make the given expression the square of a binomial is; 81

<h3>Binomial Expression</h3>

We are given the expression;

x² + 18x

Now, if we consider the binomial; x ± b

Squaring that gives us;

x² ± 2ax + b²

Comparing this expression to the one we are given we can say that;

±2ax = 18x

±a = 18/2

a = ±9

Thus,we will have;

(x + 9)² as our expression which is;

x² + 18x + 81

Therefore, the missing number is 81.

The probability for each event follows below:

P(A)= 0.23

P(E)= 0.24

P(F)= 0.28

P(N)= 0.12

P(O)= 0.07

P(S)= 0.06

<h3>Probability</h3>

Probability can be defined as the possibility that an event will occur. For an event, the probability can be found from the ratio between the number of favorable outcomes for the event and the total number of outcomes. Values of probability vary between 0 and 1.

A probability for an event is represented by P(A), P(B), etc. And exactly this that question asks for you.

1. Arrange the text of the question

North America=23 countries

South America= 12 countries

Europe= 47 countries

Asia= 44 countries

Africa =54 countries

Oceania= 14 countries

2. Find the total of countries

$N_{total}=23+12+47+44+54+14=194$
