Answer:
0.69
Step-by-step explanation:
Add both 0.49 and 0.20 (blood types)
0.49+0.20 = 0,69
The probability that a randomly chosen person can donate blood to Joe
would be 0.69.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
The distribution of blood types from a group of randomly selected people:
Blood Probability:
o 0.49
A 0.27
B 0.20
AB 0.04
Joe can safely receive blood transformations from people with blood types O and B.
The probability that a randomly chosen person can donate blood to Joe
= 0.49 + 0.20
= 0.69
