Are my answers correct? I have to go off of a wordbank.
P(Boy if favorite activity is swimming) = 8/17
P(Favorite activity is swimming if a girl) = 9/20
Use similar process for other probabilities.
WES YOUR ANSWERS ARE WRONG EXCEPT FOR ONE!!!!
idk are they
hell naw
To verify if your answers are correct, let's calculate the probabilities using the given information:
P(Boy if favorite activity is swimming):
To calculate this probability, you need the value in the cell Boys-Swimming divided by the total number of children who have swimming as their favorite activity, which is 17. Thus, the probability is 8/17 ≈ 0.47, not 0.26 as you mentioned.
P(Girl if favorite activity is sports):
To calculate this probability, you need the value in the cell Girls-Sports divided by the total number of children who have sports as their favorite activity, which is 27. Thus, the probability is 7/27 ≈ 0.26, not 0.45 as you mentioned.
P(Girl if favorite activity is reading):
To calculate this probability, you need the value in the cell Girls-Reading divided by the total number of children who have reading as their favorite activity, which is 6. Thus, the probability is 4/6 ≈ 0.67, not 0.20 as you mentioned.
P(Boy if favorite activity is sports):
To calculate this probability, you need the value in the cell Boys-Sports divided by the total number of children who have sports as their favorite activity, which is 27. Thus, the probability is 20/27 ≈ 0.74, not 0.67 as you mentioned.
P(Favorite activity is swimming if a girl):
To calculate this probability, you need the value in the cell Girls-Swimming divided by the total number of girls, which is 20. Thus, the probability is 9/20 ≈ 0.45, not 0.27 as you mentioned.
P(Favorite activity is reading if a boy):
To calculate this probability, you need the value in the cell Boys-Reading divided by the total number of boys, which is 30. Thus, the probability is 2/30 ≈ 0.07, not 0.47 as you mentioned.
P(Favorite activity is swimming if a boy):
To calculate this probability, you need the value in the cell Boys-Swimming divided by the total number of boys, which is 30. Thus, the probability is 8/30 ≈ 0.27, not 0.74 as you mentioned.
P(Favorite activity is reading if a girl):
To calculate this probability, you need the value in the cell Girls-Reading divided by the total number of girls, which is 20. Thus, the probability is 4/20 = 0.20, which is correct.
Therefore, some of your answers are incorrect, and the correct probabilities are as mentioned above.
