Answer:
Option C.
Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space (total person's hemoglobin level of 9 or above with age above 35 years)
y-----> size of the sample space (total person's age above 35 years)
so
In this problem we have
Complete the table to find the total person's hemoglobin level of 9 or above (person's age above 35)
Let
y------> total person's hemoglobin level between 9 and 11 (person's age above 35)
Find the value of x
substitute the values
