Inequality Form: m<7/3
Interval Notation: -∞, 7/3
30,77,55,71,19,40,10,5,7,6
2/5
Since 12 out of 30 marbles were black, you can assume that the percentage of black marbles in the bag is 40% (Ex: 12/30=.4) The probability that the marble you pick is black is equal to the percentage of black marbles in the bag. 40% is equal to 2/5.
