&=\frac{0.6(b-\frac{1}{2})+0.4(a-b)}{b}\\ In this article, I will list 12 questions in probability for you to practice. Primary … $$R\sim\mathrm{Bernoulli}(p=0.4), \quad \mbox{that is, }\mathbb{P}(R=-1)=0.6,\:\:\mathbb{P}(R=1)=0.4.$$ Previous Sample Space Practice Questions. $$X=\mbox{"Volume of skimmed milk in a carton",} \qquad \mbox{with }\mu_{X}=500,\:\:\sigma_{X}=10.$$, $$Y=\mbox{"Volume of full-fat milk in a carton",} \qquad \mbox{with }\mu_{Y}=495,\:\:\sigma_{Y}=10.$$, $$R\sim\mathrm{Bernoulli}(p=0.4), \quad \mbox{that is, }\mathbb{P}(R=-1)=0.6,\:\:\mathbb{P}(R=1)=0.4.$$, $$Z=\mathbf{1}_{\{R=-1\}}X+\mathbf{1}_{\{R=1\}}Y.$$, \begin{align} Important Questions on Conditional Probability is available on Toppr.
