An oil company is drilling for oil at three sites. According to geological tests, the probabilities of

astra-53 [7]

Answer:

Step-by-step explanation:

Given

Probability of finding oil at site 1 is 0.30

Probability of finding oil at site 2 is 0.15

Probability of finding oil at site 3 is 0.20

Probability of Finding oil at all three sites

i.e. oil is present in all three sites simultaneously

$=0.3\times 0.15\times 0.20=0.009$

Probability of not finding oil at any of these sites $=(1-0.3)\cdot (1-0.15)\cdot (1-0.2)=0.476$

Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites

i.e. $A'\cap B'\cap C'$

Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

$A\cup B' \cup C'$ or

$'\cup B \cup C'$ or

$A'\cup B' \cup C$

<h3>Area of composite figure</h3>

A composite figure is made up of different shapes and hence their area might be difficult to determine.

In order to determine the area of such a complex shape, the area of the individual shapes is first determined and then sum up. The sum of their areas will give the area of the composite figure

For your neighbour, he can find the area of the individual shapes the backyard is made up of, then take the sum.
