Question

A bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow. A marble is drawn at random. What is the probability that it is not white? Be sure to reduce.

Answer 1

4/5 probability

Explanation:

There are 2 white out of 10, and 8 of the marbles are not white, so you divide the number of non-white marbles (the 'possibility') by the total number of marbles = 8/10. To reduce, divide by 2 and you'll get your answer.

Answer 2

4/5

Explanation:

A bag contains 10 marbles. Four of them are red, three blue, two white, and one yellow,

P( not white) = number of marbles not white / total

= ( 4red+3blue+1yellow)/10

= 8/10

= 4/5
