Answer:
1) 125
2) 1
3) 27
Step-by-step explanation:
1) 5*5*5=
125
2) whenever there is an exponent of 0, the number is 1
3) 3*3*3=
27
3a + 6b = 45
2a - 2b = -12....multiply by 3
----------------
3a + 6b = 45
6a - 6b = - 36 ...(result of multiplying by 3)
---------------add
9a = 9
a = 1
3a + 6b = 45
3(1) + 6b = 45
3 + 6b = 45
6b = 45 - 3
6b = 42
b = 7
solution is : (1,7)

Probability=number of specific outcomes/total possible outcomes
And the probability of two events happening at the same time is P(1)*P(2), or the product of the probabilities of each event...
In this case:
P(primary color)=3/6=1/2
P(head)=1/2
P(primary and head)=(1/2)(1/2)=1/4
