Maria has a bag with 6 red marbles , 6 blue marbles , and 4 green marbles . Without looking Maria pick one marble. She does not
podryga [215]
40%

The probability of her getting a red marble is the number of red marbles divided by the number of total marbles. Since she picked a green marble first, we must subtract one marble from the total number of marbles, so that the total # of marbles is 6 + 6 + 4 = 16 - 1 (green marble) = 15. Since there are 6 red marbles, our probability is 6/15 or 2/5. Converted to percentage form, this is 0.4 —> 40%

A pencil and an eraser cost 1.10 together. if the pencil costs one dollar more than the eraser how much does the eraser cost
Kazeer [188]

1 pencil + 1 eraser = $1.10


Pencil cost $1 more than the eraser.

⇒ If we take away $1 from the total, both the pencil and the eraser will cost the same.

⇒ $1.10 - $1.00 = $0.10


Divide by 2 to find the cost of the eraser.

⇒$0.10 ÷ 2 = $0.05


Find the cost of the pencil, which is $1 more than the eraser.

⇒ $0.05 + $1 = $1.05


Answer: The eraser costs $0.05
