Answer:
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.
4/5
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
