the correct option is b.explanation
evolution is a biological phenomena which descries how the heritable characteristics of a species change over successive generations. these characteristics change as a result of a mutation, natural selection or genetic recombination (to list a few).
darwin's theory of evolution explained how this phenomena occurs with respect to natural selection. the theory goes on to explain how a species diverges from a common ancestor into two or more different species (meaning different species may have common ancestor). this is a slow process as it can take thousands of years.
hope this !
you can't see heat from a stove or electric in a wire and chemical energy well you can't see the actual chemical compound of something can you but you can see actual light coming from the sun or a light bulb. and for proof just search light energy and it tells you directly.
should be your answer
answer: the correct answer is option a.
we have been given that
probability that the land has oil == 45% = 0.45
accuracy rate of the kit indicating the oil in the soil == 80 %= 0.80
rate of the kit indicating no oil in the soil = 1 - 0.8 = 0.2
probability of the land has oil and test kit predicts that there is no oil: (and means multiplication, so we will multiply the above two probabilities)
hence, the probability that the land has oil and the test predicts that there is no oil is 0.09.
