PROBABILITY

==============================

» What is the probability of picking a red ball in a jar with 8 White balls, 2 red balls ,and 10 blue balls?

» Using the formula of probability, we can identify the chances of picking a red ball.

[tex] \: : \implies \sf \large P(E)= \frac{\# \: of \: favorable \: outcomes}{Total \: \# \: of \: possible \: outcomes} [/tex]

[tex] \implies \sf \large P(E)= \normalsize\frac{\# \: of \: Red \: Balls}{Total \: \# \: of \: Balls} \\ [/tex]

[tex] \implies \sf \large P(E)= \normalsize \frac{2}{8 \: + \: 2 \: + \: 10} \\ [/tex]

[tex] \implies \sf \large P(E)= \normalsize \frac{2}{20} \\ [/tex]

» Simplify.

[tex] \implies \sf \large P(E)= \normalsize \frac{2 \div 2}{20 \div 2} \\ [/tex]

[tex] \implies \sf \large P(E)= \normalsize \frac{1}{10} \\ [/tex]

Final Answer:

[tex] \tt \huge» \: \purple{B. \: P(E) = \frac{1}{10} }[/tex]
