Answer:

P(not A) = 8/9

Step-by-step explanation:

To write a simple probability, write a fraction. The bottom is all the possibilities, here there are 9. So put a 9 on the bottom. Then on top write how many ways the event can happen. There are 8 ways you can land on "Not A" (that is: B, C, D, E, F, G, H, I) So 8 goes on top. Simplify if possible. 8/9 cannot be simplified.

P(not A) = 8/9

what is the chance to get 4 items with 10% chance of each occurring, while there 8 items in total with other 4 items having a 90

densk [106]

Step-by-step explanation:

Simple events in probability have a certain chance of happening. For example, a 10% chance of rain today. When two or more probabilities are possible, they are added together to get the total probability. A 10% chance of snow and a 15% chance of hail would mean a 10% + 15% = 25% chance of bad weather. This article will show you how to find the probability of a simple event happening.

Kamal invested $1200 in a savings acc paying 1.8% per yr compound interest.

Greeley [361]

Answer:

A = $1311 and 96cents

Step-by-step explanation:

$A = P(1 + \frac{r}{n})^{nt}$

P = $1200

r = 1.8% = 0.018

n = 1 (compounded yearly)

t = 5

$A = 1200(1 + 0.018)^5 = 1200 \times(1.018)^5 = 1311. 96$

3. Make a class frequency table using 2 rule of the following data. Find the Mean and make a Cumulative frequency Histogram [10]

sashaice [31]

Answer: Mean = 284

Step-by-step explanation:

Data:

125, 126, 127, 127, 137

201, 202, 207, 211, 215, 218, 224, 237, 261

301, 308, 310, 315, 330, 330, 360, 380, 393, 394

401, 401, 410, 421, 422, 424

Class Frequency Table:

$\boxed{\begin{array}{c|c|c}\underline{\text{Intervals}}&\underline{\text{\qquad Frequency\qquad}}&\underline{\text{Cumulative Frequency}}\\0-49&0&0\\50-99&0&0\\100-149&5&5\\150-199&0&5\\200-249&8&13\\250-299&1&14\\300-349&6&20\\350-399&4&24\\400-449&6&30\\450-499&0&30\end{array}}\\.\qquad \qquad \qquad \qquad \quad \ 30$

Mean:

The sum of the numbers divided by the quantity of numbers:

8518/30 = 283.933

Cumulative Frequency Histogram:

Create the graph based on the Interval and Cumulative Frequency of the class frequency table above. (see image)
