Question

A jar of marbles contains the following: two red marbles, three white marbles, five blue marbles, and seven green marbles.What is the probability of selecting a red marble from a jar of marbles?

Answer 1

`(2)/(17)`

Step-by-step explanation

Given;

`\begin{gathered} n(Red)=2 \\ n(white)=3 \\ n(blue)=5 \\ n(green)=7 \end{gathered}`

The total number of marble is;

`n(Total)=2+3+5+7=17`

Recall, the probability of an event can be calculated by simply dividing the favorable number of outcomes by the total number of the possible outcome

Hence, the probability of selecting a red marble is;

`\begin{gathered} Prob(Red)=(n(Red))/(n(Total)) \\ =(2)/(17) \end{gathered}`
