Answer:

Probability of no one picking up a defective product = 571 / 1540

Step-by-step explanation:

Total number of items = 22

non-defective items = 22-3 = 19

Probability of all three picking up non-defective products

= 19/22 * 18/21 * 17/20

= 969/1540

Probability of at least one picking up a defective product

= 1 - 969/1540

= 571/1540

(=0.371, approx.)

YES, this is correct. All quadrilaterals whether is a trapezoid, parallelogram, rhombus and others, they are all polygons and all they have 4 sides and 4 angles. We know that a polygon is a figure with at least three sides and three angles.

Not all polygons are quadrilateral, this is also correct since some polygons have five or more sides and angles.

Find the seventh term of the
jekas [21]

Answer:

T_7 = \frac{64}{729}

Step-by-step explanation:

Given

a =1

r = \frac{2}{3}

Required

Determine the 7th term

The nth term of a gp is:

T_n = a * r^{n-1

So, we have:

T_7 = 1 * \frac{2}{3}^{7-1

T_7 = 1 * \frac{2}{3}^{6

T_7 = 1 * \frac{2^6}{3^6}

T_7 = 1 * \frac{64}{729}

T_7 = \frac{64}{729}
