Answer:
So, the probability is P=0.018.
Step-by-step explanation:
We know that Pedro drives the same route to work on Monday through Friday.
We know that there is a 55% chance that the light will be red.
We get that p=55%=0.55.
We conclude that the probability of not being a red light:
q=1-p=1-0.55=0.45.
We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:
So, the probability is P=0.018.
Answer:
a) 0.06 = 6% probability that a person has both type O blood and the Rh- factor.
b) 0.94 = 94% probability that a person does NOT have both type O blood and the Rh- factor.
Step-by-step explanation:
I am going to solve this question treating these events as Venn probabilities.
I am going to say that:
Event A: Person has type A blood.
Event B: Person has Rh- factor.
43% of people have type O blood
This means that
15% of people have Rh- factor
This means that
52% of people have type O or Rh- factor.
This means that
a. Find the probability that a person has both type O blood and the Rh- factor.
This is
With what we have
0.06 = 6% probability that a person has both type O blood and the Rh- factor.
b. Find the probability that a person does NOT have both type O blood and the Rh- factor.
1 - 0.06 = 0.94
0.94 = 94% probability that a person does NOT have both type O blood and the Rh- factor.
