A) \[\frac{7}{9}\]
B) \[\frac{5}{9}\]
C) \[\frac{2}{3}\]
D) \[\frac{4}{9}\]
Correct Answer: D
Solution :
[d] Total possible outcomes are |
\[\{(1,1),(1,4),(1,9),(2,1),(2,4),(2,9),(3,1),(3,4),(3,9)\}\]i.e., 9 |
Favourable outcomes are |
\[\{(1,1),(1,4),(2,1),(3,1)\}\]i.e., 4 |
\[\therefore \,\,\,\,\,\,\,\,\,\,\,p(xy<8)=4/9\] |
