Question

the table displays the distribution of blood types a, b, ab, and o to the presence of the rh factor that is either present (pos.) or absent (neg.).
use the information in the two - way table to complete the statement.
the probability that a person has a positive rh factor given that he/she has type o blood is percent.
there is a greater p for a person to have a than a person to have a positive rh factor gi o blood.

Explanation:

Step1: Recall conditional probability formula

Conditional probability formula is \(P(A|B)=\frac{P(A\cap B)}{P(B)}\). Here, event \(A\) is having positive Rh factor and event \(B\) is having type \(O\) blood. \(P(A\cap B)\) is the probability of having both positive Rh factor and type \(O\) blood (\(0.37\)), and \(P(B)\) is the probability of having type \(O\) blood (\(0.45\)).

Step2: Calculate the probability

\(P=\frac{0.37}{0.45}\approx 0.8222\). Convert to percentage: \(0.8222\times100 = 82.22\%\approx82\%\)

Answer:

82
