2/10 (or 1/5 ) Times 2/10 (or 1/5)
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.
14n+ 4 = 2( 7n + 2 ) ; the factors are 2 and ( 7n + 2 ) ;
This equation simplified would be
-y(-5y+6)
