Random variable
Explanation:
A function that assigns a numerical value to each outcome of an experiment is described as a random variable. Random variables helps to determine the outcome of a random event.
- Example of a random event is tossing of die, casting of a coin.
- Random variables ascribe numerical values to the outcome of an experiment.
- They are often used in probability to determine the extent of the certainty of an experimental procedure.

Answer:
A=60.06 x 10⁻⁵ m²
Explanation:
Given that
Weight of the person = 864 N
Weight of the bike = 85 N
The total weight ,car + bike ,Wt= 864 + 85 N
Wt = 949 N
2 p = 949 N
The weight on the each tire(F) = 474.5 N
P = 7.9 x 10 ⁵ Pa
We know that
Force = Pressure x Area
F= P A
By putting the values
474.5 = 7.9 x 10 ⁵ A
A=60.06 x 10⁻⁵ m²
Therefore area of contact A
A=60.06 x 10⁻⁵ m²

Explanation:
Given:
ρ = 13.6 x 10³ kg/m³, density of mercury
W = 6.0 N, weight of the mercury sample
g = 9.81 m/s², acceleration due to gravity.
Let V = the volume of the sample.
Then
W = ρVg
or
V = W/(ρg)
= (6.0 N)/[(13.6 x 10³ kg/m³)*(9.81 m/s²)]
= 4.4972 x 10⁻⁵ m³
Answer: The volume is 44.972 x 10⁻⁶ m³
