you're most welcome.. Happy studying at Openstudy... :)
Okay, these events, are they dependent or independent?
I would say the same, in that case we may use the rule of multiplication of independent probabilities: When two events, A and B, are independent, the probability of both occurring is \[\Large P(A|B)=P(A) \times P(B)\]
so multiply .3*.1 ??? and that will be my answer
I would think so yes, if they are indeed independent events. a little unsure
thank you , can you help me with another one?
Yea sure. Gotta be going soon though.
Josh believes the Spanish club students at his school have an unfair advantage in being assigned to the Spanish class they request. He asked 500 students at his school the following questions: "Are you in the Spanish club?" and "Did you get the Spanish class you requested?" The results are shown in the table below: Spanish Club Not in Spanish Club Total Received Spanish class requested 265 100 365 Did not get Spanish class requested 70 65 135 Total 335 165 500 Help Josh determine if all students at his school have an equal opportunity to get the Spanish class they requested. Show your work and explain your process for determining the fairness of the class assignment process.
Heard about hypothesis testing and its relation to probability?
i dont think so
Then I don't know how you want to evaluate it really. And nor do I got the time right now. Sorry.
