Answer:
The interval that would represent the middle 68% of the scores of all the games that Riley bowls is (147, 173).
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 160, standard deviation of 13.
Middle 68% of the scores of all the games that Riley bowls.
Within 1 standard deviation of the mean, so:
160 - 13 = 147.
160 + 13 = 173.
The interval that would represent the middle 68% of the scores of all the games that Riley bowls is (147, 173).
The distance between the two is 70
Answer:
Therefore the probability that the card is not brown is
.
Step-by-step explanation:
Probability: Probability is the ratio of the favorable outcome to the total outcome.

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.
Total number of cards= (2+4+6)=12
∴P(getting a brown card)



∴P(not getting a brown card)
=1 - P(getting a brown card)


Therefore the probability that the card is not brown is
.
