What is 50000x700? and 100x123,478
jok3333 [9.3K]
The question given here has two parts and each part has to be answered separately. In case of both the multiplications, the answer might look to be huge but by applying a simple technique, anybody can do these multiplications without the help of any calculator.
Now let us take the case of first multiplication that is given:
50000 * 700
= 35000000
In this case all the zeroes present has to be written first and then 7 and 5 should be multiplied and put. This will get the answer easily.
Now we take the second multiplication given:
100 * 123478
= 12347800
In this case also the zeroes are simply put on the right side of the number 123478.

Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, on
jolli1 [7]

Answer:

See explanation

Step-by-step explanation:

<h3 /><h3>Step 1</h3>

Miguel wins $2 is if he pulls two chips with the number 1.  

<u>Probability of winning is: </u>

  • 2/4 * 1/3 = 1/6  as there are 4 chips in total

<u> Probability of loosing is:</u>

  • 1- 1/6 = 5/6
<h3 /><h3>Step 2</h3>

<u>Missing values we found in the step 1, can be populated in the table:</u>

  • Xi === 2 === -1
  • P(Xi) === 1/6 === 5/6

<u>Expected Value as per table data:</u>

  • 1/6*2 + 5/6*(-1) = -1/2

Expected value is $1/2 loss each time he plays

<h3 /><h3>Step 3</h3>

To make the game fair, the expected value should be zero.

<u>Then as per the calculation above, let's replace 2, with x, and find its value.</u>

  • 1/6x + 5/6*(-1) = 0      
  • 1/6x = 5/6                  
  • x= 5  

So the amount should be $5 to make the game fair.
