Answer:

Step-by-step explanation:

Alright, lets get started.

8\frac{1}{2}-3\frac{1}{?}=5\frac{3}{12}

These are mixed number given.

Suppose the complete mixed number of second place is x.

Converting mixed numbers into fractions.

\frac{17}{2}-x=\frac{63}{12}

Adding x in both sides

\frac{17}{2}=x+\frac{63}{12}

x=\frac{17}{2}-\frac{63}{12}

Making common denominator

x=\frac{102}{12}-\frac{63}{12}

x=\frac{39}{12}

x=\frac{13}{4}

In mixed number form:

x=3\frac{1}{4}

So comparing with given equation, the '?' sign will be equal to 4.

Hence the answer is 4    :  Answer

Hope it will help :)

Answer:

If you roll two dices, you can get as results all numbers from 2 to 12. Among these, the prime numbers are 2, 3, 5, 7, 11. The probability you get each of them is: 2: you can get it only as 1+1, so one combination over 36 possibility. Probability: 1/36. 3: you can get it as 1+2 or 2+1, so two combinations over 36 possibility. Probability: 2/36. 5: you can get it as 1+4, 2+3, 3+2, 4+1, so four combinations over 36 possibility. Probability: 4/36. 7: you can get as 1+6, 2+5, 3+4, 4+3, 5+2, 6+1, so six combinations over 36 possibility. Probability: 6/36. 11: you can get it as 5+6 or 6+5 so two combinations over 36 possibility. Probability: 2/36. The total probability of getting a prime number is the sum of the probabilities, which is 15/36. So m=15, n=36 and 10m+n=150+36=186.
