I’m pretty sure the answer is 1,108.8 if it’s wrong my bad
First you can add 50 dollars to 450 dollars which is 500 then divide that 500 by 2 and that is 250
It would be 9 flowers because 4 times 9 equals 36 which means that each arrangement would have an even amount.
Using Venn probabilities, it is found that the probability that he receives an offer on at least one of the jobs is given by:
D. 0.80
<h3>What is a Venn probability?</h3>
In a Venn probability, two non-independent events are related with each other, as are their probabilities.
The "or probability" is given by:

In this problem, we have that:
- 50% chance of getting an offer on Job A, hence P(A) = 0.5.
- 60% chance of getting an offer on Job B, hence P(B) = 0.6.
- 30% chance of getting an offer on both jobs, hence
.
Then, the probability of getting an offer on at least one job is:

Hence option D is correct.

Answer: Option #1: ( -2 , -1 )
Step-by-step explanation:
5(-2) - (-1) = 9
