Evaluate 20.003+[(30.1+5.75)-6.87

48.983.

Step-by-step explanation:

(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).

Using order of operations (PEMDAS):

20.003 + [(30.1 + 5.75) - 6.87]     Work out the inner parentheses first:

= 20.003 + [35.85 - 6.87]             Now the outer parentheses:

= 20.003 + 28.98

= 48.983.

48.983

Step-by-step explanation:

according to BODMAS rule

bracket first

20.003 +(35.85) - 6.87

then addition

(20.003+45.85)_6.87

(55.853) - 6.87

at last subtraction

(55.853_6.87)

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! )
