Answer:
S={(heart), (diamond), (club), (spade)}
Step-by-step explanation:
In probability, a set is a well-defined collection of objects, product of an independent successful operation.
A sample space is the combination of all possible outcomes in an operation, so in this case, when we select one card and record the denomination, then we need to check what characteristic from the card are we looking for, from the problem we can see that is the denomination by itself, not the color, the number of the card, or anything else, and we only have 4 options of denomination so the sample space would be:
S={(heart), (diamond), (club), (spade)}

All you have to do is multiply 55.8 by .62 to get the answer which is 34.596 but I rounded up it to 34.60
Answer:
15.9
Step-by-step explanation:
so -9.7 is 9.7 jumps form 0 and same for 6.2 is 6.2 jumps from 0
9.7 + 6.2 = 15.9
the distance between -9.7 and 6.2 is 15.9
You would get 28/27 or 1 1/27
The threshold of interest ($13,000) is $6,000 or 3 standard deviations below the mean ($19,000). The rule you are asked to use tells you that 99.7% of the distribution lies within 3 standard deviations of the mean. This tells you that 0.3% lies outside. Since the distribution is symmetrical, half those values are 3 standard deviations above the mean and the half of interest are 3 standard deviations below the mean.
The percentage of buyers who paid less than $13,000 is about 0.3%/2 = 0.15%, according to the rule you are to use.
