Belleville High School offers classes on three different foreign languages. Let A be the event that a student is in eleventh gra
de, and let B be the event that a student is enrolled in French class.Which statement is true about whether A and B are independent events? A and B are independent events because P(A∣B) = P(A).
A and B are independent events because P(A∣B) = P(B).
A and B are not independent events because P(A∣B) ≠ P(A).
A and B are not independent events because P(A∣B) ≠ P(B).
Independent events:→ Two events are known to be independent of each other, if the probability of one event is not affected by the probability of the other event . For example,Selecting a red color ball from 6 balls (3 blue +3 black) is independent of selecting a chair in which there are(5 black +5 grey).
There are two events
A= A student is in eleventh grade.
B=A student is enrolled in French class
P(A∣B)=Probability that student is in 11 nth class and he or she has taken french.
Two events A and B are independent ,if
P(A∩B)=P(A)*P(B) and,
Option A:→ A and B are independent events because P(A∣B) = P(A).
Pam and her brother both open savings accounts. each begin with a
balance of $0. For every $2 is that Pam saves in her account her brother
saves $5 in his account
P:bro=2:5 when P=40 what is bro?
2/5=40/b times 5b both sides 2b=200 divide 2 b=100 bro has $100 not sure what tape diagram is
