Answer:
0.470
Step-by-step explanation:
Given that on average, Chance has noticed that 19 trains pass by his house daily (24 hours) on the nearby train tracks.
For 8 hour period the average would be 19/3
X no of trains passing is Poisson with average 19 trains per hour
P(X=x) = 
Required probability = the probability that at most 6 trains will pass his house in a 8-hour time period
=the probability that at most 6*3 trains will pass his house in a 8*3-hour time period
=P(X
18)
=0.4695
=0.470
92 divided by 18 =
5.11111111111
since we're talking about people we round it to the nearest whole number, which is 5
So five students in each group.
which leaves 1 student out of the group
1x15=15 there is nothing else
Y^2-5y+1- a= 4y^2-y+7
a=y^2- 4y^2-5y+y+1-7
a= -3 y^2 - 4y - 6 this is the polynomial
