-Given that a student correctly uses the following form of Bayes' theorem,
$\mathrm{P}\left(\mathrm{R}_{1} \mid \mathrm{T}\right) =\frac{\mathrm{P}\left(\mathrm{T} \mid \mathrm{R}_{1}\right) \mathrm{P}\left(\mathrm{R}_{1}\right) }{\mathrm{P}\left(\mathrm{T} \mid \mathrm{R}_{1}\right) \mathrm{P}\left(\mathrm{R}_{1}\right) +\mathrm{P}\left(\mathrm{T} \mid \mathrm{R}_{2}\right) \mathrm{P}\left(\mathrm{R}_{2}\right) +\mathrm{P}\left(\mathrm{T} \mid \mathrm{R}_{3}\right) \mathrm{P}\left(\mathrm{R}_{3}\right) }$ ,
Make a precise statement about the value of $P\left(R_{1} \cap R_{2} \cap R_{3}\right)$ .

A) $\mathrm{P}=1$
B) $0 \leq \mathrm{P} \leq 1$
C) $0<\mathrm{P}<1$
D) $\mathrm{P}=0$
