Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65
Well, we know that cube has 6 sides
So, the least number of different colors needed to paint a cube so no adjacent faces have the same color is :
At least 3

Answer:
(a)p(3,3)=0.0416
(b)p(4,11)=0.0002
Step-by-step explanation:
Number of Customers, X
Y = the total number of packages to be wrapped for the customers waiting in line
a. P(X = 3, Y = 3)
p(3,3) means that there are 3 customers with one gift each
The probability of this event happening:
p(3,3)=0.0416
b. p(4,11)
For 4 people to have a total package of 11, there must be 3 customers with 3 packages each and 1 customer with 2 packages,
The probability of this happening is:
