Answer:
In the procedure
Step-by-step explanation:
we have
<em>System 1</em>
Ax+By=C -----> equation A
Lx+My=N -----> equation B
<em>step 1</em>
Multiply equation B by -1 both sides
(-1)*(Lx+My=)N*(-1)
-Lx-My=-N ------> equation C
<em>step 2</em>
Adds equation A and equation C
Ax+By=C
-Lx-My=-N
----------------
Ax-Lx+By-My=C-N
(A-L)x+(B-M)y=C-N -----> equation D
step 3
An equivalent system (System 2) is formed with
Ax+By=C -----> equation A
(A-L)x+(B-M)y=C-N -----> equation D
We solve this question building the probabilities outcomes.
According to this, it is found that the probability is: 0.023, given by option C.
The probabilities are:
- 40% = 0.4 probability of the air being humid.
- If humid, 5% = 0.05 probability of a tornado.
- 100 - 40 = 60% = 0.6 probability of the air being dry.
- If dry, 0.5% = 0.005 probability of a tornado.
What is the probability that there was a tornado in Tulsa on July 1, 2019?
Two possible outcomes:
- 0.05 of 0.4(humid)
- 0.005 of 0.6(dry)
Thus:

0.023 probability, and the correct answer is given by option C.
