Answer:
p² -16pq + 36q²
Step-by-step explanation:
Given
(-
p + 6q)²
= (-
p + 6q)(-
p + 6q)
Each term in the second factor is multiplied by each term in the first factor, that is
-
p(-
p + 6q) + 6q(-
p + 6q)
=
p² - 8pq - 8pq + 36q² ← collect like terms
=
p² - 16pq + 36q²

Step-by-step explanation:
Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6
Even= 2,4,6
Odd = 1 ,3 , 5
Probability of getting even =
Probability of getting odd = 
4 dices are rolled together
a)P(3 even and 1 odd numbers)
P(3 even and 1 odd numbers)=
P(3 even and 1 odd numbers)=
b)P(2 even and 2 odd numbers)
P(2 even and 2 odd numbers)=
P(3 even and 1 odd numbers)=
=0.375
