The area of a wall to be tiled in 1.5 metres by 2.5 metres. Tiles are 50cm by 50cm
The tiles are £0.99 each.
How much will the tiles cost in pounds

Step-by-step explanation:

Given that,

The area of a wall to be tiled in 1.5 metres by 2.5 metres.

Tiles are 50cm by 50cm

The tiles are £0.99 each.

We need to find the cost of the tiles in pounds.

The area of tiles will be :

Cost of 1 time = £0.99

So, for 2500 cm², total cost will be :

Hence, this is the required solution.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

c. (3,2,6) is the answer.
