1) Option III

2) Option I and II

3) The probability of events is 2.5%.

4) The probability of events is

5) Option D

Step-by-step explanation:

1) To find : Which events are dependent?

Dependent events are those which depends of first trial i.e, conditional.

I. and II. Flipping a coin or picking a number are not dependent. 

The probability of the result is the same every time.  It only changes if you leave out what you picked the first time, because then the total number of possibilities is different.

According to reasoning,

III. picking odd numbers, without replacement is dependent because you

don't replace what you draw the first time. 

Therefore, Option III is correct.

2) To find : Which events are independent?

Independent events are those which is not dependent on each other.

By the same reasoning above, I. and II. are independent i.e, flipping a coin multiple times  and picking coins, with replacement.

Therefore, Option I and II are correct.

3)  Given : A spinner numbered 1 through 10 is spun 3 times.

To find : What is the probability of spinning a 5, then an even number, and then another even number?

Solution :

Total number of outcomes = {1,2,3,4,5,6,7,8,9,10}=10

Probability of spinning a 5 first time is

Probability of an even number (2, 4, 6, 8 or 10) the second time

Probability of an even number (2, 4, 6, 8 or 10) the third time

Probability of all 3 events

Therefore, The probability of events is 2.5%.

4)  Given : A bag contains 3 red, 5 brown, and 4 yellow potatoes.

To find : What is the probability of randomly choosing 2 yellow potatoes without replacement?

Solution :

Total number of outcomes = 3+5+4=12

Probability of getting 1st yellow potato  

Probability of getting 2nd yellow potato

Probability of choosing 2 yellow potatoes without replacement

Therefore, The probability of events is

5) To find : What is the probability of getting heads, tails, and heads, in that order, when flipping a coin?

Solution :

Total number of outcomes are {HHH, HHT, HTH, HTT, THH, THT,TTH,TTT}=8

Favorable outcome of getting heads, tails, and heads - HTH=1

Probability of getting of getting heads, tails, and heads

Flipping a coin is an independent event as event A is not dependent on event B.

Therefore, The probability of events is and independent.

So, Option D is correct.
