Answer:
c. 99.72% of the time the random variable assumes a value within plus or minus 1 standard deviation of its mean
Step-by-step explanation:
In a normal distribution, the shape is bell-shaped; this means it is symmetric.
The area under a normal distribution will always be equal to 1.
The mean, median and mode in a normal distribution are equal.
However, the data assumes values within 1 standard deviation above or below the mean 68% of the time, not 99.72% of the time. This is the characteristic that doesn't fit.
Probability of getting an even number:
Total Outcomes: 6
Desired Outcomes: 2, 4, 6; 3 total
3/6 or 1/2 1/2=.5
Probability of a Club:
Total Outcomes: 52
Desired Outcomes: Clubs; 13 total
13/52 or 1/4 1/4=.25
Probability of event A * Probability of event B
.5 * .25=.125
Probability of rolling an even number and pulling a club from a deck of cards is 0.125 or 1/8
