Answer:

Probability states the ratio of number of favorable outcomes to the total number of possible outcomes.

i.e,  probability = \frac{Number of favourable outcomes }{Total number of possible outcomes}

A bag contains:

Brown marble = 4

Green marbles = 3

Red marbles = 2

Purple marble = 1

Total number of possible outcomes = (4+3+2+1) = 10 marbles

P(Brown marbles) = \frac{4}{10}=\frac{2}{5} = 40\% = 0.4

P(Green marbles) = \frac{3}{10} = 30\% = 0.3

P(Red marbles) = \frac{2}{10}=\frac{1}{5} = 20\% = 0.2

and

P(Purple marbles) = \frac{1}{10}= 10\% = 0.1

Aleks04 [339]

Answer:

The answer is that each brick weights .515 pounds.

Step-by-step explanation:

10 to the 3rd power is 10^3 = 1000 bricks.

The weight of the full truck minus the weight of the empty truck is the weight of the bricks:

6755 - 6240 = 515 pounds of bricks

Pounds per brick:

515 / 1000 = .515 pounds per brick.

Hope this helps! Have a great day!
