Answer:
There are [tex]7050[/tex] available license plates for the people of Venn.
Step-by-step explanation:
We know that the first character of the pattern is one of 47 Egyptian hieroglyphs, the second is one of 30 emojis, and the third character is one of 5 polygons.
Let's suppose that we have the first part of an experiment that can occur in [tex]n_{1}[/tex] ways. Now, the second part of the experiment can occur in [tex]n_{2}[/tex] ways. Following the idea, the nth part of the experiment can occur in [tex]n_{s}[/tex] ways.
The total ways in which the whole experiment can occur can be calculated as : [tex]n_{1}[/tex] x [tex]n_{2}[/tex] x . . . x [tex]n_{s}[/tex]
This is the idea of the multiplication principle.
Now in the exercise we have 47 Egyptian hieroglyphs for the first character, 30 emojis for the second character and finally 5 different polygons for the last character.
The total number of 3 character license plates available to the people of Venn can be calculated as :
[tex](47).(30).(5)=7050[/tex]
There are [tex]7050[/tex] license plates.
