1. The probability that a person who exists older than 35 years has a hemoglobin level between 9 and 11 exists at 0.284.
2. The probability that a person who exists older than 35 years has a hemoglobin level of 9 and above exists at 0.531.
Let the number of the person who is older than 35 years have a hemoglobin level between 9 and 11 be x.
From the given table it is clear that the total number of the person who is older than 35 years exists 162.
75+x+40 = 162
x+116 = 162
x = 162-116
x = 46
The number of people who are older than 35 years has a hemoglobin level between 9 and 11 exists at 46.
1. The probability that a person who exists older than 35 years has a hemoglobin level between 9 and 11 exists
P = Probability who is older than 35 years has a hemoglobin level
between 9 and 11 / Person who exists older than 35
P = 46/162 = 0.284
The probability that a person who is older than 35 years has a hemoglobin level between 9 and 11 exists at 0.284.
2. Person who is older than 35 years has a hemoglobin level of 9 and above exists 46 + 40 = 86.
The probability that a person who exists older than 35 years has a hemoglobin level of 9 and above exists
P = Probability who is older than 35 years has a hemoglobin level
between 9 and above / Person who is older than 35
P = 86/162 = 0.531.
The probability that a person who is older than 35 years has a hemoglobin level of 9 and above exists at 0.531.
