First calculate the probability of type AB, which is the remainder after subtracting types A, B and O.
P(AB) = 1-(0.34+0.12+0.5) = 1-0.96 = 0.04
Anti-b will react with types B and AB, so
P(reaction) = P(B)+P(AB) = 0.12 + 0.04 = 0.16
Answer: For this person, the probability of reaction with anti-b is 0.16
The answer is A because they are parts of algae
I believe your answer would be:
A. Fossils.
Explanation:
Because they are the preserved remains or traces of animals, plants, and other organisms from the past. They're also important evidence for evolution because they show that life on earth was once different from life found on earth today.
