In the general population, one woman in eight will develop breast
cancer. research has shown that 1 woman in 600 carries a mutation of
the brca gene. eight out of 10 women with this mutation develop
breast cancer.
a) find the probability that a randomly selected woman will develop
breast cancer given that she has a mutation of the brca gene. b) find the probability that a randomly selected woman will carry the mutation of the brca gene and will develop and will develop breast cancer? c) are the events of carrying this mutation and developing brest cancer independent or dependent?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

this is false ^.^ lol
