Answer:
2 5/12
Step-by-step explanation:
you can combine two fractions if they have the same denominator (bottom number) by adding the numerators (top numbers) and keeping the bottom number the same.
1/12+4/12 is the same as 1+4 you just put the sum over 12:
2 1/12+4/12= 2 5/12
it can also be written as 29/12
If the E(X) = 1 then that means it has a 100% which is incorrect.
Each
block has an equal probability to contain the error so 1/3 because you
choose 2/6.
You keep the same sign. So:-
4 + 4 = 8 and
--4 + -4 = -8
