Answer:
mutually exclusive
Step-by-step explanation:
The formula of interest is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, we have ...
9/10 = 2/5 + 1/2 - P(A and B)
Solving for P(A and B), we get ...
P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10
P(A and B) = 0
__
Events are mutually exclusive when <em>they can never happen at the same time</em>. That is, P(A and B) = 0.
The events A and B are mutually exclusive.
Answer:

Step-by-step explanation:



Subtract 59.99 from 64.19.
64.19 - 59.99 = 4.20
<u>The tax she paid was $4.20, so now we need to find the percentage.</u>
Divide 4.20 by 59.99.
4.20 ÷ 59.99 = 0.07
Multiply 0.07 by 100 to find the percentage.
0.07 × 100 = 7
<u>The sales tax in the area was 7%.</u>
