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.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
