If number `x` is chosen fromthe numbers 1,2,3, and a number `y` is selected from the numbers 1,4,9. Then, `P(x y<9)dot` `7/9` (b) `5/9` (c) `2/3` (d) `1/9`

Explanation

Number `'x'` can be selected in three ways and corresponding to each such way there are three ways of selecting number y therefore, the two numbers can be selected in `9` ways as listed below:


`(1,1),(1,4),(1,9),(2,1),(2,4),(2,9),(3,1),(3,4),(3,9)`


Total number of outcomes `=9`


The product `xy` will be less than `9`, if `x` and` y `are chosen in one of the following ways:
