A container has 3 apple juice boxes, 4 grape juice boxes and 5 orange juice boxes. Alex picks one juice box, drinks it and then

Eduardwww [97]

Hey!

Grape over total: $\frac{4}{12}$

After he drinks 1, there will be 1 less. That means it will be over 11

Orange over total: $\frac{5}{11}$

Now multiply the fractions

$\frac{4}{12} \times \frac{5}{11} = \frac{20}{132} \rightarrow \frac{10}{66} \rightarrow \frac{5}{33}$

That means the probability is: $\frac{5}{33}$

Good luck and hope this helps! :)

Answer:

x = 8.2

Step-by-step explanation:

As indicated on the supplied diagram, the measure of arc GH is ...

GH = 360° -83° -115° = 162°

The inscribed angle at F is half this measure, so we have ...

(10x -1)° = 162°/2

10x = 82 . . . . . . . . add 1 and simplify

x = 8.2 . . . . . . . . . divide by 10
