The partially filled contingency table gives the frequencies of the data on age (in years) and sex from the residents of a retirement home. 60-69 70-79 over 79 total male 1 9 5 female 19 2 4 total what is the probability that a resident is female ? round your answer to three decimal places if necessary. a. 0.635 c. 0.62 b. 0.629 d. 0.625 select the best answer from the choices provided a b c d

Option:D

Step-by-step explanation:

We know that probability of a function is the ratio of favourable cases to the total number of cases possible.

here we have to find the probability that a resident is female.

so it's

here the total number of females are=19+2+4

                                                             =25

and the total number of males=1+9+5

                                                  =15

Hence, total number of people=25+15=40

so

                              =0.625

Hence option D is correct.
