Agreat way to visualize conditional probabilities is to think about a bag of marbles. in our initial bag of marbles we have 2 blue marbles, and 3 red marbles. therefore, we have a 2/5 chance of selecting a blue marble, and a 3/5 chance of selecting a red marble. selecting marbles when selecting a second marble, the probabilities have changed. we now have conditional probabilities for all of the different possible scenarios. marble image tree 2 based on the image above, what is p(b|a), the probability of pulling out a red marble, after having already pulled out a blue marble? p(a) is the probability of selecting a blue marble and p(a and b) is the probability of selecting a blue marble and a red marble. p(a and b) is different than p(b|a), the conditional probability of selecting a red marble, when a blue marble has already been selected. report as a decimal rounded to 2 decimal places, not a percent.

The tuition costs, c, for a local community college are modeled by c(h) = 250 + 200h, where h represents the number of credit hours taken. the local state university has tuition costs, s, modeled by the function s(h) = 300 + 180h. how many credit hours will a student have to take for the two tuition costs to be equal? round the answer to the nearest tenth of an hour.

Isuck at math ; ^; m a student solved this problem and said the answer is 3 feet. chase had a roll of ribbon that contained 7 7/8ā feet of ribbon. he cut off one piece that was 3 5/8ā feet long and another piece that was 1 1/4ā feet from the roll. how much ribbon was left on the roll? is the student's answer reasonable? yes, the answer is reasonable. no, the answer is not reasonable. it should be about 2 feet. no, the answer is not reasonable. it should be about 13 feet. no, the answer is not reasonable. it should be about 4 feet.
