anything raised to the power of 0 is 1
P ( A ) = 0.45 - probability that the land has oil,
P ( B ) = 0.8 - probability that the test predicts it
P ( A ∩ B ) = P ( A ) · P ( B ) = 0.45 · 0.8 = 0.36
Answer: The probability that the land has oil and the test predicts it is 36 %.

Answer:
<u>The measurement of the circumference of this circle is 23.9 ft.</u>
Step-by-step explanation:
Let's recall that the circumference formula is:
C = 2πr or C = πd, where:
r = radius = 7.6/2 = 3.8 ft
d = diameter = 7.6 ft
In consequence, we have:
C = 3.14 * 7.6
C = 23.864
<u>C = 23.9 ft</u>
