Question

Which if the following represent valid probabilities?

• A. $\{A,D,E,F\}$
• B. $\{B,C,D,E\}$
• C. $\{B,D,E,F\}$
• D. $\{A,C,E,F\}$

Answer 1

The correct option is C $\{B,D,E,F\}$

We know that $0\le P\left(E\right)\le 1$
or, $0\%\le P\left(E\right)\le 100\%$
Hence, $\{B,D,E,F\}$ are the only valid choices.
