Jake had a bag of 50 beads, of which some are red and some are the remaining are yellow. Jake randomly pulls out a bead from the bag, , records the color, and replaces it in the bag. Jake has already recorded 6 red and 9 yellow beads. Based on the results, what is most likely the number of red beads in the bag?
Answers
Most likely the numbers of red beads in the bag are 20.
Let us consider there are x red beads and (50-x) yellow beads.
So, as given in the question, Jake pulls a total of 15 beads(6 red and 9 yellow).
So, P(r)=ed bead probability
and yellow bead probability
Now, the total number of red bead
Hence, the number of red beads in the bag is most likely to be 20.
What is probability explain?
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
How to calculate probability?
The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.
What are some examples of probability?
Example: toss a coin 100 times, how many Heads will come up? Probability says that heads have a ½ chance, so we can expect 50 Heads. But when we actually try it we might get 48 heads, or 55 heads ... or anything really, but in most cases it will be a number near 50.

If total Revenue is $3000, Cost of Goods is $1500, and total Selling Expense is $500Question: what is the Profit for the business=> The total revenue is 3 000 dollarsThe expenses:=> 1 500 dollars for gold's costs=> 500 dollars for selling expenses.Now, let's add the expenses and subtract it to the total earnings=> 1 500 dollars + 500 dollars = 2 000 dollarsNow, let's subtract:=> 3 000 dollars - 2 000 dollars = 1 000 dollars. Thus, his profit is 1 000 dollars
Answer: 1000
Step-by-step explanation: If you have 3000 take away 1500 you have 1500 then, subtract 500 you then have 1000. 1000 would be the final correct answer.

The compensation strategy is used in mathematics when taking the sum of two or more values in other to make computation easier.
- Compensation involves adjusting the value of a certain number before processing with addition in other to make the calculation easier.
- For example ; 29 + 33
- We could change the value of 29 to 30 by adding 1 ; as it is easier to sum 30 and 33.
- Then ; 30 + 33 = 63
- The added value is then subtracted from the result.
- 63 - 1 = 62
- Hence, 29 + 33 = 62
The above example is a simple way of using the compensation strategy.

Answer:
The correct answer is 250.
Step-by-step explanation:
To determine what is the total value of an operation in which the value 50 will mean its 20%, what we must do is simply multiply the value by 100, and divide it by the percentage:
(50,100): 20 =
5000: 20 =
250
In this way we verify that the total value was 250.
If you had any questions, we can calculate the% 20 of 250, to see if the result is 50:
250 0.20 = 50.
Thus we verify that the calculation was correct.
x=100%
50=20%
multiply both sides by 5
50*5=20%*5
250=100%
therefore, x=250
