Do Not Like Burgers

44

25

69

Total

76

74

150



If a student likes hotdogs, what is the probability that student also likes burgers?
93.8%
50.7%
42.1%
39.5%

Answers

Answer 1

Answer:

like burgers with the wrong total of 76/150 is 50.7%

do not like burgers with also the wrong total of 74/150 is 50% simplified

now with the right totals its 54% for liking burgers and 46% for not liking

Step-by-step explanation: 32 + 49 + 81 = 162

                                           44 + 25 + 69 = 138

right total (162) wrong total (76)

right total (138) wrong total (74)

right (300) wrong (150)

unless u simplified by 2 which is 150/300 then its right simplified

so im confused but this is my answer

Answer 2

Answer:

Years late but I'll answer anyway. It is C. 42.1%

Step-by-step explanation:

A two-way table is a bivariate table. Bivariate tables have rows and columns just as your table has.

Remember, a column is vertical and a row is horizontal. Each value in the data table is called a cell.

In this case, you have to do column relative frequency. This is a cell frequency divided by the column total. It's not as hard as it may sound.

The number of people who like hotdogs and burgers is 32, and the total for that column is 76. All you have to do is divide 32 by 76 and you have your answer.

32 / 76 = 0.421 or 42.1%
