Sagot :
Red marbles = 6
Green marbles = 10
Yellow marbles = 4
Total marbles in the bag = 20
The probability of picking a red or a yellow marble is;
[tex]\begin{gathered} Pr(\text{red or yellow)=Pr(picking red)}+Pr(\text{ picking yellow)} \\ Pr(\text{ picking red) = }\frac{n(red\text{ marbles)}}{total\text{ marbles}} \\ Pr(\text{ picking red) =}\frac{6}{20} \\ Pr(\text{ picking yellow)=}\frac{4}{20} \end{gathered}[/tex][tex]\begin{gathered} Pr(\text{ picking red or yellow)=}\frac{6}{20}+\frac{4}{20}=\frac{10}{20} \\ Pr(\text{ picking red or yellow)=}\frac{1}{2} \end{gathered}[/tex]The probability of picking a red or yellow marble is 1/2
