Answer:
The statement is False.
Step-by-step explanation:
Consider the provided information.
If a linear system has four equations and seven variables, then it must have infinitely many solutions.
We need to determine the above statement is true or false.
The above statement is false, it could be inconsistent, and therefore have no solutions,
For example:
Hence, there is no solution.
Answer:
As per the statement:
Let Event A represents the probability that a vehicle is white and Event B represents the probability that it is a pick up truck .
then;
and
It is also given that:
The Probability that it is a white pick up truck is 0.06.
⇒ where
represents that it is white pick up truck.
We have to find the the probability that the vehicle is white {given that the vehicle is a pickup truck}
We use the formula:
where
represents that the pick up truck vehicle is white.
Substitute the given values we get;
Therefore, the probability that the vehicle is white, given that the vehicle is a pickup truck is 0.4
