1. Given that we have 4 green marbles, 4 pink marbles and 5 orange marbles, let us first find the probability that we select a pink marble.
We can find this by taking the number of pink marbles and dividing it by the total number of marbles:
Pr(P) = 4/(4 + 4 + 5)
= 4/13
2. Now that we have chosen one pink marble, we must find the probability that we choose an orange marble from the remaining marbles (4 green, 3 pink, 5 orange):
Pr(O) = 5/(4 + 3 + 5)
= 5/12
3. If we want to find the probability of picking a pink marble and then an orange marble, we must multiply the probabilities we have found in the first two steps:
Pr(P)*Pr(O) = (4/13)*(5/12)
= 20/156
= 5/39
Therefor, there is a probability of 5/39 that you pick a pink and then an orange marble.

Answer:
x = 4. (Answer B)
Step-by-step explanation:
Combine the x-terms on the left side: -x + 3x = 2 + 6.
Simplifying further, 2x = 8, or x = 4. (Answer B)
Answer:
x = 36.9
Step-by-step explanation:
Use the sine function if you know the length of the opposite side and the hypotenuse. Plug your values into the equation: sine (x) = opposite ÷ hypotenuse. Say that the length of the opposite side is 6 and the length of the hypotenuse is 10. Divide 6 by 10, which is equal to 0.6. Now you know that sine (x) = 0.6 which is the same as x = sine^-1 (0.6).
Steps:
sin (x) = 6/10
sin(x) = 0.6
then we do sin^-1(0.6), which equals 36.869897645844 ° (degrees)
36.869897645844 ° (degrees) rounded to the nearest tenth is 36.9
so x = 36.9
