Having at least one headache and taking a daily vitamin are stochastically dependent events.

Step-by-step explanation:

A group of patients were asked whether they take a daily vitamin and whether they had at least one headache in the past week. The table shows the probabilities of result.

                  Had  at least         Had no     Total

                 one headache     headache

Takes a

daily

vitamin           0.15                         0.35        0.5

Does not

take a daily

vitamin            0.3                          0.2         0.5      

Total                0.45                       0.55        1

Now,P(The patient takes a daily vitamin) P(The patient had at least one headache in the past week)

=

= 0.225 ≠ 0.15 = P(The patient takes a daily vitamin and had at least one headache in the past week)

Hence, having at least one headache and taking a daily vitamin are dependent events.

ian gonna lie that is way to much

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
