Question

Intro to probability

Answer 1

red marbles = 97

blue marbles = 16

white marbles = 53

total marbles = 97 + 16 + 53 = 166

Therefore, the probability it is not a red marble can be calculated below

`\begin{gathered} \text{probability it is red=}(97)/(166)=0.58433734939 \\ \text{probability it is not red=1-}(97)/(166)=(166-97)/(166)=(69)/(166)=0.4156626506=0.4157 \end{gathered}`
