no solution.

Valentinooo:
I am challenging you tonight, go and revise probability, then come back to modify this your post.

gr8cany:
Then I got it, because I said can't be solved

Valentinooo:
I still disagree sir. Or you should reframe the question.

Let me ask you this.

An unbiased coin is tossed three times, what is the probability of getting three heads?

An unbiased coin is tossed threw times, what is the probability of getting three heads?

Kareayo:
sector

gr8cany:
Tossing the two 6times gives 6x4 which equals 24 possible outcome

Kareayo:
also, this doesn't work for terminating decimals.. It only works for recurring decimals

Valentinooo:
The number of times has effect.
If you toss a coin once, there is 2 outcomes. (H, T)
If you toss it twice, you have 4 outcomes (HH, HT, TH, TT)

If you toss it three times, you have 8 OUTCOMES (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT)

If you toss it four times, you have 16 OUTCOMES.

Notice that number outcomes depends on the number of throw.
No of outcome = 2ⁿ

For 2 coins,

If you toss them once, it's just like when you throw a coin twice. There will be four outcomes.

Kareayo:
but it is not in all cases that we multiply by 100. It can be 10 or 100 or 1000 depending on the numbers of digits after decimal

Kareayo:
this is a recurring decimal, I.e 4.353535...

For recurring decimal, the denominator is always 9 or 99 or 999 etc depending on the number of digits recurring..

In this case, our denominator is 99 since it is only two digits that are recurring (3 & 5)

To get numerator, this will be (the main number without the decimal) minus (the actual number before the decimal). I.e 435 - 4 = 431

Therefore 4.35... = 431/99

NDSMELODY:
Mr shape pls check my solution i have posted two

NDSMELODY:
4+0.35= 4 +35/100

take lcm,400+35/100 = 435/100=4.35

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are
2
numbers to the right of the decimal point, place the decimal number over
10
2

(
100
)
. Next, add the whole number to the left of the decimal.
