Answer:
The mean is more useful in this case because it would give an average value of the accidents for example 3 accidents per year but the median would give the middle value which may be 5 or greater or much lesser than the average. It would not give an approximate value of occurrences.
Step-by-step explanation:
Mean is the averaage of all the values.
Median is the value of the data which gives an estimate of the middle value. Middle values can be different than the average values.
The mean is
1) rigorously defined by a mathematical formula.
2) based on all the observations of the data
3) affected by extreme values
The meadian is
1) computed for open end classes like income etc.
2) not rigorously defined
3) is located when the values are not capable of quantitative measurment.
4) is not affected by extreme values.
The mean is more useful in this case because it would give an average value of the accidents for example 3 accidents per year but the median would give the middle value which may be 5 or greater or much lesser than the average. It would not give an approximate value of occurrences.
Answer:
1/169
Step-by-step explanation:
52 cards in a deck, 13 are diamonds
P(diamond) = number of diamonds/ total
= 13/52 = 1/13
Replace the card
52 cards in a deck, 13 are diamonds
P(diamond) = number of diamonds/ total
= 13/52 = 1/13
P (diamond, replace, diamond) = 1/13 * 1/13 = 1/169
