19 - 3.
Your answer is 16.
Answer:
The probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.
Step-by-step explanation:
As the event is indicated as I for the drivers who are intoxicated, the value of I¯ is for the drivers who are not intoxicated. Its value is calculated as follows
P(I¯)=1-P(I)
P(I¯)=1-0.00589
P(I¯)=0.99411
So the probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.
To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.
The formula of a sphere is:

Let's take 丌 as 3.14
The volume of the balloon with 4cm radius:

The volume of the balloon with 8cm radius:

As we can see,
267.94668 × 2 = 535.89 ≠2145.56
Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.
