2. Transistors are of three types, type P, type Q, and type R. A grade A box of transistors contains 5 P's, 3Q's, and 1 R. A grade B box contains 2 P's, 3 Q's and 4 R’s. How many boxes
of each grade can be filled if the total numbers of P, Q, and R available are 80, 75, 70
respectively, and all transistors are used?
2) Grade A = 10 and Grade B= 15

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! )

it should be a and d. lmk if i'm wrong xd

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
