For the given experiments there are following outcomes.
A) Independent
b) Dependent
C) Dependent
D) Dependent
E) Independent

<h3>What is probability?</h3>

Probability can be defined as the ration of favorable outcomes to the total number of events.

For A)
A coin is tossed and a dice is flip. Both the event are independent of each other.

For B)
Choosing of clips have same total number of events that why both the events are dependent to each other.

For C)
It also have same number of total samples cause both cherries and nuts contained chocolate belongs to the same box. That's why its also dependent.

For D)
It
is also dependent because the total number of sample is same for both the marbles.

For E)
It is independent, because for every box that picked reduces the size of sample and probability of picking new box wont depends on previous box.


Thus, this is how events are dependent and independent

Given that sin θ = 3/4 and θ is in Quadrant II:<br> Find cos θ.
julsineya [31]

this is for the Sin

*Remember that sin = opposite / hypotenuse*

a² + b² = c² (where a and b are legs and c is the hypotenuse)

From the picture, you can see:

a = 3

c = 4

Plug these into the equation and solve for b.

* a² + b² = c² *

step 1: 3² + b² = 4²

step 2: 9 + b² = 16

step 3: b² = 16 - 9

step 4: b² = 7

step 5: √(b²) = √7

step 6: b = ± √7

FOR COS:

From the picture,  you can see that if θ is in quadrant II, b has to be negative.

b = -√7 = adjacent

Remember that cos θ = adjacent / hypotenuse.

cos θ = adjacent / hypotenuse

cos θ = (-√7 / 4)
