In-s [12.5K]

Answer:

188 balloons

Step-by-step explanation:

First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:

9632 / 86 = 112 balloons

She sold 112 balloons.

We know that she threw 76 balloons away, therefore, the number of balloons she bought was:

When a man observed a sobriety checkpoint conducted by a police department, he saw 671671 drivers were screened and 77 were arr

kifflom [539]

Answer:

$P(\overline W)=0.98957$

Step-by-step explanation:

Number of drivers Screened = 671

Number Arrested for Driving While Intoxicating = 7

If the W denotes the event of screening a driver and getting someone who is intoxicated.

The Probability of W, $P(W)=\frac{7}{671}=0.01043$

The Probability $P(\overline W)$ is the probability of the event of screening a driver and getting someone who is not intoxicated. Simply put, it is the Probability of the Complement of W.

From Probability Theorem,

$P(W)+P(\overline W)=1\\Since \: P(W)=0.01043\\0.01043+P(\overline W)=1\\P(\overline W)=1-0.01043\\=0.98957$
