A) P = 0.0875

B) P = 0.092

C) P = 0.0625

D) P = 0.053

E) P = 0.100

F) P = 0.105

G) P = 0.1225

H) P = 0.1105

Step-by-step explanation:

A) The probability of picking a blue shirt is $\frac{7}{20}$ . After replacing it, there are still 20 shirts, so the probability of picking a yellow shirt is $\frac{5}{20}$ . As the blue shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

B) The probability of picking a blue shirt is $\frac{7}{20}$ . Without replacing it, there are 19 shirts, so the probability of picking a yellow shirt is $\frac{5}{19}$ . As the blue shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

C) The probability of picking a yellow shirt is $\frac{5}{20}$ . After replacing it, there are still 20 shirts, so the probability of picking a yellow shirt is $\frac{5}{20}$ . As the yellow shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

D) The probability of picking a yellow shirt is $\frac{5}{20}$ . Without replacing it, there are 19 shirts, so the probability of picking a yellow shirt is $\frac{4}{19}$ (as there is one less yellow shirt). As the yellow shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

E) The probability of picking a yellow shirt is $\frac{5}{20}$ . After replacing it, there are still 20 shirts, so the probability of picking a white shirt is $\frac{8}{20}$ . As the yellow shirt AND the white shirt must be picked then you multiply the two probabilities together.

F) The probability of picking a yellow shirt is $\frac{5}{20}$ . Without replacing it, there are 19 shirts, so the probability of picking a white shirt is $\frac{8}{19}$ . As the yellow shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

G) The probability of picking a blue shirt is $\frac{7}{20}$ . After replacing it, there are still 20 shirts, so the probability of picking a blue shirt is $\frac{7}{20}$ . As the blue shirt AND the yellow shirt must be picked then you multiply the two probabilities together.

H) The probability of picking a blue shirt is $\frac{7}{20}$ . Without replacing it, there are 19 shirts, so the probability of picking a blue shirt is $\frac{6}{19}$ (as there is one less blue shirt). As the blue shirt AND the blue shirt must be picked then you multiply the two probabilities together.

Answer from: Quest

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq and the angle ∠orq are opposite, therefore:

$m\angle opq+m\angle orq=180\°\\\\m\angle opq+ (2x + 16)\°=180\°$

then, $m\angle opq+ (2x + 16)\°=180\°$ can be used to d to calculate the measure of ∠opq

Quadrilateral opqr is inscribed in circle n, as shown below. which of the following could be used to
