Answer:
0.999
Step-by-step explanation:
Assuming that there are ten questions.
This yields:
Each answer has an equal chance of being selected.
Therefore, the probability of the answer = [tex]\frac{1}{2}[/tex]
But we assume 10 questions, therefore, the probability will be given as follows:
P (Ans) = [tex](a^{x})[/tex]
= [tex](\frac{1}{2}) ^{10}[/tex]
= 0.000977
This is the probability of getting them all wrong.
The probability of getting the answer right is given by p(Right answer) = 1 -0.000977 = 0.9990
