Question

A bag with 12 marbles has 5 blue marbles, 3 yellow marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is blue? Write your answer as a fraction in simplest form. 0 8 08 X Ś ?

Answer 1

Step 1

Given;

Step 2

Probability of an event is given as;

`P(event)=\frac{number\text{ required events}}{Total\text{ number of events}}`
`Number\text{ of required events=number of blue marbles=5 blue marbles}`
`Total\text{ number of events=Total number of marbles=12 marbles}`

Thus, the probability of that the marble is blue is;

`P(blue)=(5)/(12)`

Answer;

`P(blue)=(5)/(12)`
