In a random sample of 500 people, 210 had type O blood, 223 had type A, 51 had type B, and 16 had type AB. Set up a frequency distribution for the data. Find the probability that a randomly selected person from the population has the given blood type. (Round your answer to 2 decimal places). Type O

The frequency distribution for the data is

     Blood Type (X)              Frequency(F)             Relative Frequency P(X)

                   O                                  210                                    0.42

                   A                                   223                                   0.45

                   B                                      51                                     0.102

                  AB                                     16                                     0.032  

Total(T)                                                500

The  probability is  

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  500

     The number with blood type O is  k =  210

       The number with blood type A  is a =  223

       The number with blood type AB is  c = 16

        The number with blood type B is  b =  51  

Generally the frequency table for this data is  

 Blood Type (X)              Frequency(F)             Relative Frequency P(X)

                   O                                  210                                    0.42

                   A                                   223                                   0.45

                   B                                      51                                     0.102

                  AB                                     16                                     0.032  

Total(T)                                                500

Generally the probability that a randomly selected person from the population has type O is    

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
