P(volleyball and baseball) = 4/200 x 100 = 2%
P(volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.
Thus, 25% of students participate in either volleyball or baseball.
There are 28 combinations.
Step-by-step explanation: Initially, each of the seven bins holds one ball, leaving two remaining. If both are placed in the same bin, that offers 7 options. Conversely, if each remaining ball is positioned in different bins, the combination comes down to: 21 + 7 = 28 ways.
Step-by-step explanation:
Given are
Sides of the triangle measure 4 units, 6 units, and 7.21 units.
We need to compute the area of a circle whose circumference matches the triangle's perimeter.
The triangle's perimeter corresponds to the circle's circumference.
4 + 6 + 7.21 = 2πr, where r is the radius of the circle.
r = 2.73 units
Circle's area is:

or
A = 24 square units
Thus, the circle’s area is 24 square units.
Option D is indeed correct, as it ensures that the post's point is equidistant from the ground, maintaining a perpendicular angle at two points on the surface.
