a spiner has 0 to 9?

oh ok

I don't know if i typed the question to make sense

- xapproachesinfinity

is the question as it is written or you change it?

- xapproachesinfinity

well let's
P((1,3) and (1,6) this the desired prob

- xapproachesinfinity

P((1,3) and (1,6))=P((1,3))P((1,6))

- anonymous

So it gives me the spinners i drew and it gives me a Chart |dw:1434422759820:dw|

- xapproachesinfinity

now we find p((1,3))
we need to all the possible pairs here

- xapproachesinfinity

hmm how is that helpful?

- anonymous

and it just asks what is the probability of spinning double threes

- xapproachesinfinity

i would do it this way (1,1)(1,2)(1,3)(1,4)(1,5)(1,6)
(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)
(3,1)(3,2) (3,3)(3,4)(3,5)(3,6)
and go on
out of this how many are (1,3)
i think (3,1) is different

- xapproachesinfinity

same go with (1,6)

- xapproachesinfinity

or does it matter from which spinner gives 1 or 3?

- xapproachesinfinity

if that matter we need to narrow that list down

- anonymous

Nope it doesn't matter. Thank you! Ill do that!

- xapproachesinfinity

just to clear one misundertanding
i said P(1.3 and 1,6)
that is not the case
they are asking for two probabs
p(1,3)
p(1,6)
two distinct questions

- xapproachesinfinity

well i think it is clear now :)

The probability of spinning a 1 on the spinner of 3 is 1/3. The probability of spinning a 1 on the spinner of 6 is 1/6. Therefore the probability of a double 1 is given by
\[\large \frac{1}{3} \times \frac{1}{6}\].
The probability of a double 2 will be the same as for a double 1, and the probability of a double 3 will also be the same as the probability of a double 1.
The events 'double 1', 'double 2' and 'double 3' are mutually exclusive, therefore the probability of spinning doubles is given by
\[\large P(doubles)=3\times\frac{1}{3}\times\frac{1}{6}\]
