Question

You randomly draw a marble out of a bag that contains 20 total marbles. 12 of the marbles in the bag are blue.

What is P(draw a blue marble)?
If necessary, round your answer to 2 decimal places.

Answer 1

`P(Blue)=0.60`

Explanation:

Probability:
`Probability\ of\ an\ event=(favourable\ outcome)/(total\ outcome)`

`Total\ marbles=20\\\\Hence\ total\ outcomes=20\\\\Blue\ marbles=12\\\\Hence\ favourable\ outcomes=12\\\\P(Blue)=(12)/(20)\\\\P(Blue)=(2* 6)/(2* 10)\\\\P(Blue)=(6)/(10)\\\\P(Blue)=0.60`
