The square below represents one whole.
What percent is represented by the shaded area?
%

70%

Step-by-step explanation:

Each blue line represents 10%.  Since there are 7 blue lines, we just multiply 10% by 7 and we get 70%

70%

Step-by-step explanation:

7 out of 10 rectangles were filled so that's 7/10. 7/10 also equals 70/100. Therefore it's 70 out of 100 or 70%.

There are 6 possible outcomes {1,2,3,4,5,6} that you could get from a 6-sided die.

Of these, {1,2,3} are less than 4 i.e. there are 3 outcomes that satisfy the requirement out of 6.

Thus, the probability that you get a number less than 4 on rolling a 6-sided die once would be 3/6 = 1/2
