Marley is an avid birdwatcher and is trying to estimate the number of bluejays living in his region he traps 22 Blue Jays and ta

qwelly [4]

Answer:

15 Blue Jays

Step-by-step explanation:

Number of Blue Jays tagged = 22

Number of Blue jays captured = 550

Estimate of the Blue Jay population = 825

We need to find out how many Blue Jays out of 550 were tagged ones. Remember that in the beginning there were no tagged Blue Jays and Marley tagged 22 of them. This means total number of tagged Blue Jays in the entire population is 22. Rest of the blue Jays are not tagged. Marley calculated the estimated Blue Jay population using the proportions.

Assume that from 550, x Blue Jays were tagged. Out of 825 Blue Jays, 22 are tagged. The proportion of tagged Blue Jays in 550 must be equal to the proportion of tagged Blue Jays in entire population. i.e.

$x : 550 = 22 : 825\\\\ \frac{x}{550}=\frac{22}{825}\\\\ x=\frac{22}{825} \times 550\\\\x =14.7$

Since, the number of Blue Jays cannot be in decimal, we round it up to the nearest integer 15.This means, out of 550 trapped 15 Blue Jays were the tagged ones. Based on this Marley estimated the Blue Jays Population size.

lilavasa [31]

Answer:

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.

Step-by-step explanation:

Conditional Probability

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 problem:

Event A: Company fires the CEO

Event B: Shares increase by more than 5%.

Probability of a company firing it's CEO:

35% of 100 - 4 = 96%(shares did not increase by more than 5%).

60% of 4%(shared did increase by more than 5%).

So

$P(A) = 0.35*0.96 + 0.6*0.04 = 0.36$

Intersection of events A and B:

Fires the CEO and shared increased by more than 5%, is 60% of 4%. So

$P(A \cap B) = 0.6*0.04 = 0.024$

Probability that the shares of a company that fires its CEO will increase by more than 5%.

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.024}{0.36} = 0.0667$

0.0667 = 6.67% probability that the shares of a company that fires its CEO will increase by more than 5%.
