Answer: C

Step-by-step explanation:

$\frac{3a}{4}+\frac{2a}{3}-\frac{a}{12}$

Find the least common denominator of 4, 3, and 12.

4-3-12 | 3

4-1-4 | 4

1-1-1 |-------- 12

The first fractions needs to be multiplied by 3, and the second fraction, by 4

$(\frac{(3a)*3}{(4)*3})+(\frac{(2a)*4}{(3)*4})-\frac{a}{12}$

Solve;

$\frac{9a}{12}+\frac{8a}{12}-\frac{a}{12}$

Add the fractions with positive signs and subtract the one with negative sign.

$\frac{(9a+8a)-a}{12}$

Solve;

$\frac{17a-a}{12}=\frac{16a}{12}$

Simplify by 4;

16/4=4

12/4=3

$\frac{4a}{3}$

Answer:

0.0078125

Step-by-step explanation:

If the probability of flipping a fair coin (mentally) correctly for 1 row is 0.5, then the probability of flipping it correctly for 2 rows is

0.5 * 0.5 = 0.25

for 3 rows: 0.5*0.5*0.5 = 0.125

...

For 7 rows:

$0.5*0.5*0.5*0.5*0.5*0.5*0.5 = 0.5^7 = 0.0078125$
