Answer 3

hello? anyone ?

Answer 4

first, what you need to do is figure out how many pencils there are in all. Then, figure out how many yellow pencils there are. then you need to figure out how many combinations there are of getting a yellow pencil AND the coin landing on heads.

Answer 6

hey @drawwithapurpose can you explain that in simple words or just say the answer if you know it with all do respect tho

Answer 7

I would give you the answer but direct answers are against the CoC. But i can simplify what i said. first add up all the pencils (20) then find out how many yellow pencils there are (6). so that would give us 6 out of 20 for pencils. okay?

Answer 8

20-6 = 14

Answer 9

not quite. it would be 6/20. next we need to add the probability of pencils and coin sides to each coin. 6 yellow pencils = 12 sides of the coin (six top and six bottom). then we add the number of the bottom side to the number of pencils.

Answer 10

so it could be c ?

Answer 16

Omg thx!

Answer 17

No problem :)

Answer 18

C is incorrect, multiply the probabilities:

6/20 * 1/2 =

Answer 19

Since the chance of a coin landing tails up is 1/2
