Question
The frequency distribution of blood groups of 187 people is given. A person is selected at random. Calculate the probability that the randomly selected person has O blood group.
Blood Group Frequency:
A: 84 B: 58 AB: 15 O: 30 a person is selected at random. Calculate the probability that the rundrede selected person has O blood group
A.The probability that the randomly selected person has O hhs gong 0.0642
B. The probability obability that the randomly selected person has O blood group is 0.6442
C. The probability that the randomly selectest person has O Mood group is 0.5742
D. The probability that the tandomly selected person has O blocal group s 0.4234
Solution
The probability of an event is calculated by dividing the number of favorable outcomes by the total number of outcomes. In this case, we want to find the probability that a randomly selected person has O blood group.
Step 1: Find the total number of people. This is given as 187.
Step 2: Find the number of people with O blood group. This is given as 30.
Step 3: Divide the number of people with O blood group by the total number of people to find the probability.
So, the probability that the randomly selected person has O blood group is 30/187 = 0.1604.
Therefore, none of the given options A, B, C, or D is correct.
