<span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333.....
the good explanation of your answer is that 0.999999....is equal to 1
we can prove it by the following way:
let x=0.9999....
then 10x = 9.999999.....
subtract we will get 10x - x = 9.9999....- 0.99999......
which gives us 9x = 9 and therefore x =1
i hope this will help u with your confusion....... :)</span><span>

Answer: Our required probability is 
Step-by-step explanation:
Since we have given that
Number of coins = 3
Number of coin has 2 heads = 1
Number of fair coins = 2
Probability of getting one of the coin among 3 = 
So, Probability of getting head from fair coin = 
Probability of getting head from baised coin = 1
Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

Hence, our required probability is 
No, the answer is not 
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
