Answer:
17
Step-by-step explanation:
The median value of any given set of data is the middle value occupied by any numbers when the data set is arranged in either lowest to highest or vice versa order.
The given data set consists of following numbers
8, 11, 19, 17, 23, 25, 11
So total there are 7 numbers
On arranging the numbers in increasing order, the following series is obtained
8, 11, 11, 17, 19, 23, 25
So the median value will lie at
position
hence, the median value is 17

Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
In this problem:
- In total, there are 8 + n sweets in the bag.
- Of those, n are red.
The probability of red is:
Supposing, we solve for n:
10n = 7n + 56
3n = 56
n = 56 / 3
n = 18.67
Since the number of red sweets would be a decimal number, the probability cannot be 7 / 10
