Total number of possible outcomes = 36

Total number of outcomes with sum even = 18

P(even) = 18/36 = 1/2

|\Omega|=6^2=36\\ |A|=\underbrace{3\cdot3}_{\text{O,O}}+\underbrace{3\cdot3}_{\text{E,E}}=18\\\\ P(A)=\dfrac{18}{36}=\dfrac{1}{2}=50\%

Please explain how to divide 1,344 by 24 using the box method? I know the answer is 56, but I am not sure how to get this answer
Maslowich

Answer:

Step-by-step explanation:

Given that divisor is 24 and dividend is 1344 and we are to use box method.

Long division is often considered one of the most challenging topics to teach. Luckily, there are strategies that we can teach to make multi-digit division easier to understand and perform.

The Box Method, or  the Area Model, is one of these strategies. It is a mental math based approach that will enhance number sense understanding. Students solve the equation by subtracting multiples until they get down to 0, or as close to 0 as possible.

For example this method is shown below:

I step is to find in multiples of 10 or 100 the greatest divisor

24) 1344( 500

      1200

      --------

        144

Step 2: Next step is to divide 144 by 24

24)144( 6

     144

      ----

         0

Thus we find that quotient is quotient in I step + quotient in 2nd step

= 50+6 = 56

and remainder is zero.

Both dice have odd numbers 1, 3, 5. The chances of getting an odd number on each number is 3/6

The probability of getting odd numbers on both is:

3/6 ⋅ 3/6 = 9/36 = 1/4
