Find the area of the following rectangle in square
ill mark forbr />
44 ft2
11 ft2
14.7 ft2
132 ft2

it is 44 ft2 i think

answer: our probability after the test that the land has oil = 0.234.

step-by-step explanation:

since we have given that

probability that the land has oil = 45%

probability that the land has no oil is given by

probability that the accuracy rate of indicating oil in the soil = 80%

probability that the test is not accurate is given by

we need to find that probability after the test that the land has oil :

as we know the formula of " bayes theorem " :

[tex]p(l/o)=0.45\ and\ p(l/not o)=0.55p(o)=0.80\ and\ p(not\ oil)=0.20p(not\ o\mid l)=\frac{p(not\ o).p(\l\mid not\ o)}{p(o).p(l\mid not\ o)+p(o).p(l\mid o)}p(not\ o\mid l)=\frac{0.20\times 0.55}{0.20\times 0.55+0.8\times 0.45}p(not\ o\mid l)=\frac{0.11}{0.11+0.6}=\frac{0.11}{0.47}=0.234/tex]

hence, our probability after the test that the land has oil = 0.234.
