Answer:
4 tens
Step-by-step explanation:
3 tens would get you $30, which is $7.80 short. If you give 4 tens you are giving $40 which is 2.20 more than $37.80, which is okay as you can probably get change and it is the least amount of tens you can give to cover the cost.
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.
