What is probability?

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The probability of the scoring scheme which has 5 choices is,

[tex]P_1=\dfrac{1}{5}[/tex]

The probability in percentage,

[tex]P_1=\dfrac{1}{5}\times100\\P_1=20\%[/tex]

The probability of the scoring scheme which has 4 choices is,

[tex]P_2=\dfrac{1}{4}[/tex]

The probability in percentage,

[tex]P_2=\dfrac{1}{4}\times100\\P_2=25\%[/tex]

The probability of the scoring scheme which has 3 choices is,

[tex]P_3=\dfrac{1}{3}[/tex]

The probability in percentage,

[tex]P_3=\dfrac{1}{3}\times100\\P_3=33.34\%[/tex]

Thus, scoring scheme is the most favorable to the test taker is that have 3 question choices or scheme D.
