G The number of people that enter on any given day is a Poisson distributed random variable with mean 10. In the cathedral are 14 donation boxes that are emptied every night. Each time a visitor enters the cathedral, they place a donation in a randomly chosen donation box, with each box equally likely to be chosen. Find the expected number of empty donation boxes at the end of the day.

x=-15

Step-by-step explanation:

8+9.8x+9=3.8x-16+3.8x

8+9=17

17+9.8x=7.6x-16

   -7.6x  -7.6x

17+2.2x=-16

-17 .          -17

-16-17= -33

2.2x=-33

/2.2    /2.2

x=-15
