A marble is selected at random from a jar containing 2 red marbles, 6 yellow marbles, and 5 green marbles. What is the probability that a) the marble is red? b) the marble is not yellow? ) the marble is either red or green? d) the marble is neither red nor green?

The 2 red marbles plus 6 yellow and 5 green equal 13 total marbles.

A) There are 2 red marbles out of the total number so 2/13 or about 15.4%

B)The colors that are not yellow are red and green. 2 Red+5 Green=7. 7/13 or about 53.8%.

C)Same as B

D)The only color not red or green is yellow. There are 6 yellow so 6/16 or 46.2%.

Hope this helps :-)

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
