3 is only a Real number because Real Numbers are made like 1,2,3... like counting meanwhile the other two, complex numbers are a real number +b(i) and imaginary numbers are anything with i. Hope this helps!
Answer:
Step-by-step explanation:
p=
,
(22+6)2-21=
44+12-21=
35=,
If you factor out the equation, you get that 35=4p(if you factor it out)
Therefore,

To solve this problem, we should note that there are:
total questions = 100
questions answered correctly = 90
questions that needed additional clues = 10
1. The first question is to find the probability that in the
third question, Mary would need additional clue. Therefore this implies that in
the first and second questions, Mary would answer it correctly. Therefore:
Probability = (question 1 answered correctly) * (question 2 answered
correctly) * (question 3 needed clue)
Probability = (90/100)*(89/99)*(10/98)
Probability = 0.08256 = 8.26%
2. The second question finds for the probability that two
consecutive needs additional clue, therefore:
Probability = (question 1 needed clue) * (question 2 needed
clue)
Probability = (10/100)*(9/99)
Probability = 9.1*10^-3 = 0.91%
