There are 45C4 = 148,995 ways to choose 4 calculators out of a group of 45.
There are 33C4 = 40,920 ways to choose 4 calculators that are not defective.
The probability that at least one is defective is (148,995 -40,920)/148,995 ≈ 0.725.
Answer:
Step-by-step explanation:
A polygon in the plane has rotational symmetry if the figure can be mapped onto itself by rotating between 0 and 360° about it's center.
So, we need to find the number of symmetrical line a regular polygon can have.
Note : A regular polygon with n sides has n lines of symmetry and order of symmetry n.
Then, let n be number of symmetrical line lines
Then,
Smallest angle of rotation about the center for which the polygon will be mapped unto itself is
360 / n
Answer:
