From total of 10000 programs only one is winning.  The probability that you will get the winning number can be calculated as the ratio between the numbers of desired events and the total numbers of events. There is only one winning number , so the ratio is : 1/10000. If you purchase two programs the probability is the sum of the two probabilities: 1/10000+1/10000=2/10000.

We are asked to solve for the probability that out from the ten thousand programs being created and printed in preparation for the basketball tournament, there will be ONE displays for the winning number. Given the condition that we will buy TWO programs, the solution is shown below:
2 in 10,000
= 2/10000
= 0.0002
= 0.02 %

The answer is 0.02% probability.

A long distance telephone company offer two plans . The deluxe plan cost $30 a month and offers unlimited long distance calling.
Gnesinka [82]

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.

There are 3,250 buttons. If they are divided into groups of 8, how many buttons are there. Interpret the remainder. Show your wo
Andre45 [30]
I am going to assume that the question is asking how many buttons are in each of the 8 groups.

To find out how many buttons are in each of the 8 groups, we simply need to divide the amount of groups by the total amount of buttons.

3250 / 8 = 406.25

That is unlikely the answer, since buttons are hard to divide into quarters.

**************

This is the more likely solution. There are 8 groups of buttons, with 3250 buttons in each group. To find the total amount of buttons, we just need to multiply the number of groups of buttons there are by the amount of buttons there are in each group.

8 * 3250 = 26000

There are 26,000 buttons total.
Hope that helped =)

Suppose a polling agency reported that 45.7% of registered voters were in favor of raising income taxes to pay down the national
sineoko [7]
<h2>Answer with explanation:</h2>

As per given , we have

p= 0.457

n= 1033

Margin of error for 99​% confidence : E= 4%=0.04

Confidence interval : p\pm E

i.e. 0.457\pm 0.04

=( 0.457- 0.04,\ 0.457+0.04)=(0.417,\ 0.497)

99% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. = (0.417, 0.497)

Interpretation : We are 99% sure that the true population proportion of registered voters who are in favor of raising income taxes to pay down the national debt lies in interval (0.417, 0.497).
