See proof below
Step-by-step explanation:
An equivalence relation R satisfies
- Reflexivity: for all x on the underlying set in which R is defined, (x,x)∈R, or xRx.
- Symmetry: For all x,y, if xRy then yRx.
- Transitivity: For all x,y,z, If xRy and yRz then xRz.
Let's check these properties: Let x,y,z be bit strings of length three or more
The first 3 bits of x are, of course, the same 3 bits of x, hence xRx.
If xRy, then then the 1st, 2nd and 3rd bits of x are the 1st, 2nd and 3rd bits of y respectively. Then y agrees with x on its first third bits (by symmetry of equality), hence yRx.
If xRy and yRz, x agrees with y on its first 3 bits and y agrees with z in its first 3 bits. Therefore x agrees with z in its first 3 bits (by transitivity of equality), hence xRz.

The volume of the right circular cone is, 131.95 cubic centimeter.
What is cone?
A cone is a smooth-tapering three-dimensional geometric object with a flat base and an apex or vertex. The base of a cone is made up of all the points on a plane other than the apex, and the apex is connected to all the other points on the base by a series of line segments, half-lines, or lines.
Here, the radius, r = 3 cm, and height h = 14 cm.
We have to find the volume of right circular cone.
Since,
Volume =
Hence, the volume of the right circular cone is, 131.95 cubic centimeter.

You have to use the multiplication rule.
The probability that the fisrt one is defective: 3/20
And the probability that the second one is also defective and you can not replace the first computer drawn is: 3/20*2/19 = 3/190 = 0.0158
