These are 6 quesitons and 6 answers.

Question 1) Estimate the probability of drawing 1 yellow marble from a box that contains 20 red marbles, 30 blue marbles, 10 green marbles, and 40 yellow marbles.

Answer: 2/5 = 0.4

Explanation:

1) Probability = number of positive events / number of possible events

2) Positivie events: extracting 1 yellow marble

3) Number of positive events = number of yellow marbles = 40

4) Number of possible events = number of total marbles = 20 + 30 + 10 + 40 = 100

5) probability = 40 / 100 = 2/5 = 0.4

Question 2. Estimate the probability of drawing 1 yellow marble from a box that contains 60 red marbles, 120 blue marbles, 30 green marbles, and 90 yellow marbles.

Answer: 3/10 = 0.3

Explanation:

1) Probability = number of positive events / number of possible events

2) number of positive events = number of yellow marbles = 90

3) number of possible events = number of marbles = 60 + 120 + 30 + 90 = 300

4) probability = 90 / 300 = 3/10 = 0.3

Question 3. Estimate the probability of drawing 1 yellow marble from a box that contains 30 red marbles, 40 blue marbles, 10 green marbles, and 20 yellow marbles.

Answer: 2/9 = 0.22

Explanation:

1) Probability = number of positive events / number of possible events

2) number of positive events = number of yellow marbles = 20

3) number of possible events = number of marbles = 90

4) probability = 20 / 90 = 2/9 = 0.22

Question 4. Estimate the probability of drawing 1 yellow marble from a box that contains 30 red marbles, 40 blue marbles, 20 green marbles, and 10 yellow marbles.

Answer: 1/10 = 0.1

Explanation:

1) Probability = number of positive events / number of possible events

2) number of positive events = number of yellow marbles = 10

3) number of possible events = number of marbles = 30 + 40 + 20 + 10 = 100

4) probability = 10 / 100 = 1/10 = 0.1

Question 5. Estimate the probability of drawing 1 yellow marble from a box that contains 16 red marbles, 32 blue marbles, 32 green marbles, and 80 yellow marbles.

Answer: 1/2 = 0.5

Explanation:

1) Probability = number of positive events / number of possible events

2) number of positive events = number of yellow marbles = 80

3) number of possible events = number of marbles = 16 + 32 + 32 + 80 = 160

4) probability = 80 / 160 = 1/2 = 0.5

Question 6. Estimate the probability of drawing 1 yellow marble from a box that contains 90 red marbles, 120 blue marbles, 30 green marbles, and 60 yellow marbles.

Answer: 1/5 = 0.2

Explanation:

1) Probability = number of positive events / number of possible events

2) number of positive events = number of yellow marbles = 60

3) number of possible events = number of marbles = 90 + 120 + 30 + 60 = 300

4) probability = 60 / 300 = 1/5 = 0.2
