Use the number 0 to represent the yellow marbles and 1 through 9 to represent the other marbles. 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. Use the numbers 0 through 2 to represent the yellow marbles and 3 through 9 to represent the other marbles. 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. Use the numbers 0 through 4 to represent the yellow marbles and 5 through 9 to represent the other marbles. 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. Use the numbers 0 through 3 to represent the yellow marbles and 4 through 9 to represent the other marbles. 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. 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.
Question 1) <span>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.
</span>
<span>Answer: 2/5 = 0.4 </span>
<span>Explanation: </span>
<span>1) Probability = number of positive events / number of possible events </span>
<span>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. </span>
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:
<span>1) Probability = number of positive events / number of possible events </span>
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:
<span>1) Probability = number of positive events / number of possible events </span>
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.
<span>Answer: 1/5 = 0.2 </span><span> </span><span> </span><span>Explanation: </span><span> </span><span> </span><span>1) Probability = number of positive events / number of possible events</span>
2) number of positive events = number of yellow marbles = 60
3) number of possible events = number of marbles = 90 + 120 + 30 + 60 = 300 <span />
