LOL, I just really want help with some questions.

amistre64 · Answer

the probability seems to be per ticket; so maybe 1/10 ?  i cant be sure becasue i tend to misread alot of these prob things

daenio · Answer

It's a binomial distribution question so I guess a formula is required.

amistre64 · Answer

whats the probability of getting a tails on your second coin toss?

amistre64 · Answer

since each toss, or each ticket,has the same chance of winning; id say the prob stays put.

daenio · Answer

Oh! I think it would be like this:
1 in 10 translates into 10%, which is 0.10.

q=1-p
   =1-0.10
   =0.90

P(x)=q^x p
      =0.90^2 (0.10)
      =0.81 (0.10)
      =0.081

it might, but i just cant read that much detail from the question to be sure
