Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inches and the
standard deviation is 4 inches, 68% of the population will have a height within
which of the following ranges?
A. 64 inches to 72 inches
B. 56 inches to 80 inches
C. 60 inches to 76 inches
D. 52 inches to 84 inches

i think the correct option is the second option.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

answer: 16
