Answer:
Estimated probability
Step-by-step explanation:
In this question Emil estimates the probability of 2 or more heads coming up in 3 coin flips.
He has a computer which randomly selects 0 or 1 three times, with 0 representing heads and 1 as tails.
From the results shown we will select the preferred events of getting 2 or more heads, means results having 2 zeros or more than 2 zeros.
Number of preferred events are = 5
And total events are = 12
Therefore estimated probability =
Probability
Therefore answer is

Answer:
option C
Step-by-step explanation:
The point slope equation of a line is given by
Where m is the slope and (x1,y1) is the point on the point
We need to write the equation in y=mx+b form
multiply -2/3 inside the parenthesis
Subtract 7 from both sides
Answer:
e) 0.14
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a driver does not have a valid driver's license.
B is the probability that a driver does not have insurance.
We have that:
In which a is the probability that a driver does not have a valid driver's license but has insurance and is the probability that a driver does not have any of these things.
By the same logic, we have that:
We start finding these values from the intersection.
4% have neither
This means that
6% of all drivers have no insurance
This means that . So
12% of all drivers do not have a valid driver’s license
This means that
So
The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about
So the correct answer is:
e) 0.14
