Two probability distribution functions are shown below relating to a group of people participating in a study. Let X="the number of movie theater visits in the last month by the subject" and let Y="the number of siblings the subject has." Assume these two random variables are independent.
X. P(x)
0. 0.05
1. 0.23
2. 0.23
3. 0.49
Y. P(y)
0. 0.26
1. 0.16
2. 0.49
3. 0.09
If we select one person at random from this group of people, what is the probability they have been to the movies twice in the last month, and have one sibling? Round your answer to 3 decimal places.
