ss7ja [257]

Answer:

89.01% probability that a flight arrives on time given that it departed on time.

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Departing on time

Event B: Arriving on time.

The probability that a flight departs and arrives on time is 0.81.

This means that $P(A \cap B) = 0.81$

The probability that an airplane flight departs on time is 0.91.

This means that $P(A) = 0.91$

Find the probability that a flight arrives on time given that it departed on time.

$P(B|A) = \frac{0.81}{0.91} = 0.8901$

89.01% probability that a flight arrives on time given that it departed on time.

Parts of Complex Numbers<br> z=4.1i+85<br> Re(z)=_____<br> Im(z)=_____

Pepsi [2]

Variable z = a+bi is normally used to represent a complex number.
where a is the real number of z (Re z) while b is the imaginary part of z (im z)
Therefore in this case; z=4.1 i +85, therefore
Re(z) =85
Im(z) = 4.1
