Answer:

  • P(E) = 1/2
  • P(F) = 11/32
  • P(G) = 1/6
  • P(EF) = 5/52
  • P(FG) = 1/32
  • P(EG) = 1/6

Step-by-step explanation:

For the sum to be even, both dice can be odd, or both even. The probability of a dice being odd is 1/2 and the same is for it to be even. Since the result of the dices are independent, we have that

P(E) = (1/2)² + (1/2)² = 1/2

Out of the 36 possible outcomes for the dice (assuming that you can distinguish between first and second dice), there are 11 cases in which one dice is a 6 (if you fix 1 dice as 6, there are 6 possibilities for the other, but you are counting double 6 twice, so you substract one and you get 6+6-1 = 11). Since all configurations for the dices have equal probability, we get that

P(F) = 11/32

The probability for the second dice to be equal to the first one is 1/6 (it has to match the same number the first dice got). Hence

P(G) = 1/6

for EF, you need one six and the other dice even. For each dice fixed as 6 we have 3 possibilities for the other. Removing the repeated double six this gives us 5 possibilities out of 32 total ones, thus

P(EF) = 5/32

If one dice is 6 and both dices are equal, then we have double six, as a result there is only one combination possible out of 32, therefore

P(FG) = 1/32

If both dices are equal, in particular the sum will be even, this means that G= EG, and as a consecuence

P(EG) = P(G) = 1/6

The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square
Leona [35]

Answer: 4x^2y^4

Step-by-step explanation:

Given

The area of the square is A=16x^4y^8

Suppose a is the side length of the square

The area of the square is given by

\Rightarrow A=(\text{side length})^2

So, we can write

\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4

length of each side is 4x^2y^4
