Agardener bought a package containing 3 squash seeds and 3 bean seeds. if just one seed is selected from the package what are the chances that it is a bean seed?

0.5

Explanation:

number of squash seeds = 3

Number of bean seeds = 3

Total number of seeds = 3 + 3 = 6

Number of seed selected = 1  

Chance to find that the seed is of bean seed

Number of ways to select a bean seed from bean seeds = 3 C 1

           =  

Number of ways to select a seed from all the seeds = 6 C 1

          = \frac{6!}{1!\times5!}=6

So, the chance that it is a bean seed = 3 / 6 = 1/2 = 0.5
