(08.02 La A cylindrical vase has a meter of 6 inches. At the bottom of the vase,
there are 7 marbles, each lameter 3 inches. The vase is filled with water
up to a height of 12 inches
Which of the following could be used to calculate the volume of water in the
vase? (6 points)

(12in) 3in) - 1.5( 3 min))
re{3in) 12in) - 1.5( 3 7in)
4
(3in) (12in) - 7( 3 1.5in)

answer:

probability distribution a is valid probability distribution.

step-by-step explanation:

the conditions   for any probability distribution to be valid is:

(1) the probability should not be negative

2)the probability of individual should be less than 1

(3)the sum of all the probabilities must be 1.

so, first two conditions in all the three cases is true.

now, we will check for (3) condition:

the sum of   all the probabilities in a is:   .42+.38+.13+.07=1

therefore, a is valid probability distribution.
