Find the probability of rolling a twelve first and then a three when a pair of dice is rolled twice?

yawa3891 [41]

Total number of possible outcomes = 36

Total number of outcomes with a sum of 12 = 1
{6,6)

Total number of outcomes with a sum of 3 = 2
{1,2}{2,1}

P(12 first, then 3) = (1/36)(2/36) = 1/648

Answer: The probability is 1/648

(3a2 + 2a - 2) - (a2 - 3a + 7)

drek231 [11]

Remember to distribute invibile -1
simlify 2nd part
-(a^2-3a+7)=-1(a^2-3a+7)=-a^2+3a-7

now we have
3a^2+2a-2-a^2+3a-7=
3a^2-a^2+2a+3a-2-7=
2a^2+5a-9

Solnce55 [7]

Answer:

A. $(x^{2/7})(y^{-3/5})$

Step-by-step explanation:

The numerator is:

$\sqrt[7]{x^2} = (x^2)^{1/7} = x^{2/7}\\$

The denominator is:

$\sqrt[5]{y^3} = (y^3)^{1/5} = y^{3/5}$

The fraction is equivalent to:

$\frac{x^{2/7}}{y^{3/5}} =$
$(x^{2/7})(y^{-3/5})$

Correct choice is A
