1 answer:
Answer:
The probability of marble getting marked as 6 is 0.9
Step-by-step explanation:
Total number of marbles = 10
The probability is the ratio of the number of elements in the event to the number of elements in the sample space.
Here the number of elements in the sample space = 10

Answer:
Area of the given figure is 51.5 square units.
Step-by-step explanation:
Area of rectangle OCBH = Length × width
= 11 × 8
= 88 square units
Area of trapezoid OGEF =
=
=
= 18 units²
Area of trapezoid GCDE =
=
= 13.5 units²
Area of triangle AFH =
=
= 5 units²
Area of polygon ABCDEF = Area of rectangle CBHO - (Area of trapezoid OGEF + Area of trapezoid GCDE + Area of triangle AFH)
= 88 - (18 + 13.5 + 5)
= 88 - 36.5
= 51.5 units²
Therefore, area of the given polygon is 51.5 units²
