Answer:
2/27
Step-by-step explanation:
This is a probability question and we are asked to estimate a particular probability. We proceed as follows:
The total number of sweets is given as 8 + 9+ 11= 28 sweets
He takes out a sweet to eat, the probability of this being a red sweet would be P(r1) = 8/28 = 2/7
Now he takes another sweet, we are asked to calculate the probability that this sweet is also red. Now after taking the first sweet, the number of sweets is now 27, while the number of red sweets is now 7. Hence the probability of having a red sweet taken in the second case would be p(r2) = 7/27
Now, the probability of both being red sweets can be calculated by multiplying both = 7/27 * 2/7 = 2/27

Area of a square is a².
4² = 16
Now find the area of the semicircle.
(πr²)/2
(3.14)(2)²/2
12.56/2
6.28
Now add the areas to find the total area.
6.28 + 16 = 22.28
Hope this helps :)
Answer:
2
Step-by-step explanation:
1250/5 = 250/5 = 50/ 5 = 10/5 = 2
So we pulled sqrt 5, sqrt 5, sqrt 5, sqrt 5
sqrt 5 * sqrt 5 = 5 (do twice)
25 sqrt 2
With the mean, you have to add up all of the numbers on the bottom, and then divide by how many there are.
