The average of six numbers is 22. The numbers are 20,17,18,24,29 and x. Find x
2 answers:
Answer:
Therefore, x = 24 .
Step-by-step explanation:
Given : The average of six numbers is 22. The numbers are 20,17,18,24,29 and x
To find : Find x.
Solution : We have given The average of six numbers is 22.
.
Mean = 22
.
On multiplying both sides by 6
22 *6 = 108 + x .
132 = 108 + x
On subtracting both sides by 108.
132 -108 = x
24 = x .
Therefore, x = 24 .

Using probability concepts, it is found that:
a) probability of drawing a card below a 6.
b) odds of drawing a card below a 6.
c) We should expect to draw a card below 6 about 4 times out of 13 attempts, which as an odd, it also 4 times for every 9 times we draw a card above 6, which is the third option.
------------------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
- In a standard deck, there are 52 cards.
- There are 4 types of cards, each numbered 1 to 13. Thus,
are less than 6.
Then:
probability of drawing a card below a 6.
Item b:
- Converting from probability to odd, it is:
odds of drawing a card below a 6.
Item c:
- The law of large numbers states that with a <u>large number of trials, the percentage of each outcome is close to it's theoretical probability.</u>
- Thus, we should expect to draw a card below 6 about 4 times out of 13 attempts, which as an odd, it also 4 times for every 9 times we draw a card above 6, which is the third option.
