Is this even mathematics?
Answer:
Step-by-step explanation:
Probability of an event is given as
P(an event) = no of time event occur / total sample space of event.
Let the total outcome be n,
Then, first situation...
If harry select 12 times, it probability is 12/n.
Second situation
Harry select 8 time, it probability is 8/n
Third situation,
Harry select 4 times, it probably is 4 / n.
Fourth situation
Harry selects 16 time, it probability is 16/n
Then, arranging from the order of highest frequency
Then,
16 / n, 12 / n, 8 / n and 4 / n

Answer:
x = 5
Step-by-step explanation:
6 + 8(x - 1) = 2(3x + 4)
We evaluate the numbers in the brackets first.
(8 × x = 8x, 8 × 1 = 8, 2 × 3x = 6x, 2 × 4 = 8)
6 + 8x - 8 = 6x + 8
The left hand side of the equation is not exactly simplified, so we will evaluate it further first.
(6 - 8 = -2)
8x - 2 = 6x + 8
Now we can start shifting the x and the numbers separately.
Note that when pushing 6x from the right side to the left side, it needs to change to a negative 6x and vice versa for -2 turning into +2.
8x - 6x = 8 + 2
Further evaluation
2x = 10
Now we can simply find x.
Note that for this, ×2 becomes ÷2 when it shifts from the left side to the right side of the equation.
x = 10 ÷ 2
Evaluate.
x = 5
