a) Attached
b) Probability of the second ball is yellow P(2y) is equal to the probability of the second ball is yellow given that the first one is black ( 0,204 ) plus the probability f the second ball is yellow given that the first one is yellow ( 0,125)
P(2y) = 0,204 + 0,125
P(2y) = 0,329
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.

Answer:
<h2>
A = 189 cm²</h2>
Step-by-step explanation:
The area of a parallelogram is equal to the product of the length of its <u>side and the height</u> of the parallelogram <u>perpendicular to that side</u>.
H = 9 cm
S = 21 cm
A = S•H = 21 cm • 9 cm = 189 cm²
