Answer:
o
Step-by-step explanation:
because 6x is B and 2 is C so that means A 0
The answer is 2 7/12. To find the answer you first find the equal denominator of 1/2 and 3/4 which is 4 because if you multiply 2 by 2 it is 4, then you multiply the 1 (numerator) by 2 to get 2 which 1/2 is 2/4, then you add 2/4 and 3/4 which is 5/4 which is equal to 1 1/4. Then you make the denominator of 1 1/4 and 1 1/3 equal, the number that both can equal is 12. You multiply 1/4 by 3 and you get 3/12, then you multiply 1/3 by 4 to get 4/12. So now you can add 1 3/12 and 1 4/12 which is 2 7/12.
Answer:
Step-by-step explanation:
From the question, we have the following condition:
We know that each student who hears the rumor tells it to a student picked at random from the dormitory (excluding, of course, himself/herself and the person from whom he/she heard the rumor)
The 3rd student can therefore tell the rumour to n-2 students but only n-3 will accept it.
Consequently, the 4th student must not tell the 1st and second students.
We can rewrite this to observe a pattern:
Hence, the probability that the rumor is told r times without coming back to a student who has already is:
