help with probability

There are 2 ways to get a positive value: (i) $\text{pos} \times \text{pos}$ or (ii) $\text{neg} \times \text{neg}$

The probability of the second case is: 

${1 \over 5} \times { 3 \over 5} = {3 \over 25}$

The probability of the second case is: 

${2 \over 5} \times { 4 \over 5} = {8 \over 25}$

Thus, the probability is ${8 \over 25} + {3 \over 25} = \color{brown}\boxed{11 \over 25}$

Thanks BuilderBoi,  you are correct of course.

I just wanted to show people how to do it with a contour map.

I really like contour maps, in this case it was probably as easy either way but sometimes contour maps make probablility questions MUCH easier.

The sample space is  5*5 = 25    (area)

The desirable area is  2*4+ 1*3 = 8+3 = 11

So  P(positive product) = 11/25
