INDEPENDENT AND DEPENDENT EVENTS

On a separate sheet of paper, tell which of the 5 pairs of events below are independent events:
 
 

1. Toss a coin. Then roll a number cube (die).

2. Choose a bracelet and put it on. Choose another bracelet.

3. Select a card. Do not replace it. Then select another card.

4. Select a card. Replace it. Select another card.

5. Pick one flower from a garden, then pick another.

On a separate sheet of paper, do the following experiments:

A dresser drawer contains one pair of socks of each of the following colors: blue, brown, red, white, and black. Each pair is folded together in matching pairs. You reach into the sock drawer and choose a pair of socks without looking. The first pair you pull out is red - the wrong color. You replace this pair and choose another pair. What is the probability that you will get the red pair of socks twice?

A bag contains 3 red, 5 white, and 4 blue marbles. Two marbles are drawn at random . The first marble is not replaced before the 2nd marble is drawn. Find the probability of each event.

Now, do the activity in the link below, record all of your answers on a sheet of notebook paper and write a paragraph describing the activity and your reaction to it.
