1. the table shows the results of drawing colored marbles from a bag. what would be expected to happen to the experimental probability of drawing a white marble as the number of draws increases? a. the experimental probability will likely decrease. b. the experimental probability will likely increase. c. the experimental probability will likely stay about the same. 2. the table shows the results of drawing colored marbles from a bag.
based on theoretical probability, which is the best prediction for the number of times a blue marble would be drawn in 1000 trials?
a.
150
b.
200
c.
250
d.
300 3.a spinner has ten equal sections labeled a through j. in 50 spins, the spinner stopped on the section labeled j 12% of the time.
which is most likely to happen in 1500 spins?
a.
the percent of times the spinner stops on j will approach 10%.
b.
the percent of times the spinner stops on j will approach 12%.
c.
the percent of times the spinner stops on j will be exactly 10%.
d.
the percent of times the spinner stops on j will be exactly 12%.

Probability is the percent of times that a certain result will happen in comparison to the other results. For example, a spinner with one blue side and one red side will have a 50% chance of landing on red, since half the spinner is red.

1. Assuming that the drawn marbles will be returned to the bag after being drawn, the percentage of white marbles in comparison to the other marbles will stay the same, and therefore, the probability of drawing a white marble will stay roughly the same.

Option C is your correct answer choice.

2. To find the probability of drawing a blue marble from the bag, we simply need to divide the number of blue marbles by the number of marbles in the bag. We know that there are 10 blue marbles, so let us add up the amounts of marbles total:

5 + 10 + 3 + 12 + 10 = 40

There are 40 marbles total.
Now, we can divide to find our probability

10 ÷ 40 = 0.25

So there is a 0.25 in 1 (25%) chance that we will draw a blue marble.

Now, to find the amount of times a blue marble will be drawn in a set amount of draws, we just have to multiply the probability by the amount of draws.

0.25 * 1000 = 250

In 1000 draws, the best prediction of how many times a blue marble would be drawn is 250.
Option C is your best answer choice.

3. We don't even need to do any calculations to solve this problem. Assuming the values do not change, the probability of the spinner landing on J will always be 12%.
Option D is your best answer choice.

And there you have it!
Hope that helped! =)

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
