Agardener bought a package containing 3 squash seeds and 3 bean seeds. if just one

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

-606.73C

Explanation:

According to coulombs law

F = kq1q2/r^2

Substitute the given value

83,506 = 9*10^9(-0.198)q2/(3004)^2

83,506 =  -1.242*10^9q2/9,024,016

-1.242*10^9q2 = 7.54*10^11

q2 = -7.54*10^11/1.242*10^9

q2 = -606.73C

hence the magnitude of the other charge is -606.73C
