Whether the events are dependent or not, the rule for conditional probability applies:
  P(a|b) = P(a∩b)/P(b)
  P(a|b)×P(b) = P(a∩b)
  0.25×0.4 = P(a∩b) = 0.1

The appropriate choice is
  C. 0.1

Productive use of machinery on a farm made it possible to decrease the number of tractors by 12 how many tractors does the farm
irina1246 [14]
So first off, the answer to this is 24 now think of x as the  real or original sum or amount, also y as the new sum or amount.
y * 1.5 is x, and y+12 is x. Now flip that to figure out what is y, also which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to minus 12, which can help you get the answer which is 24.

<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ An alternative way of finding it is to find 1%

To find 1%, divide the number by 100

200/100 = 2

Multiply this by 5:

2 x 5 = 10

It would be 10
