Answer:
True : If A and B are independent events, then P(A|B)=P(A) is true.
Step-by-step explanation:
If A and B are independent, P(A and B) = P(A) * P(B)
P(A|B) conditional probability, P(A) given B has already happened
= P(A and B) / P(B)
= P(A)*P(B) / P(B)
= P(A)
Therefore
If A and B are independent events, P(A|B)=P(A) is true.
Answer:
Mary has 12 friends, and a total of 13 people including her. Or, she has 25 friends, and a total of 26 people including her.
Step-by-step explanation:
First, we know that 26 is divisible by 1, 2, 13, and 26 because (2x13) and (1x26) both equal 26 but we know that Mary has more than 1 friend and if Mary is also added to the group where the candy is divided, that means that 1 and 2 are both out because Mary has more than 1 friend so 1 cannot be the answer and if Mary has 2 friends, that means that the candy would have to be divided 3 ways which is not possible evenly so the answer is either 12 friends or 25 friends.
Answer:
the thalia age be 19 years
Step-by-step explanation:
Let us assume her brother age be x
Now the thalia age be x - 3
Now the equation would be
x + x - 3 = 41
2x = 41 + 3
2x = 44
x = 22
thalia age be
= 22 - 3
= 19
Hence, the thalia age be 19 years
And, her brother age be 22 years
The same is to be considered
