The joint probability distribution of X and Y is shown in the following table, where X=the number of houses sold by Xavier and Y=the number of houses sold by Yasir. X Y 1 2 22 10 08 1 .25 .15 .10 2 .05 .03 .02 Note: . Use numbers only in your answer without any comas , symbols, or letters. Report numbers significant to three digits after the decimal point. For example , if the answer is &1,234.56789 write 1234.568. . If the answer is in percent, please write in proportions. i.e. if the answer is 12%, write it as 0.12. 1. What is the probability that both Xavier and Yasir will sell 1 houses? 2. What is the probability that Xavier will sell 1 house? 3. What is the probability that Xavier will sell 1 house, given that Yasir has sold two houses?4. Are sales by Xavier independent of Sales by Yasir? Yes as P(X=1/Y=2)=P(X=1) No because P(X=1/Y=2) is not equal to P(X=1)
