Best ResponseYou've already chosen the best response.0is the question as it is written or you change it?

Best ResponseYou've already chosen the best response.0well let's P((1,3) and (1,6) this the desired prob

Best ResponseYou've already chosen the best response.0P((1,3) and (1,6))=P((1,3))P((1,6))

Best ResponseYou've already chosen the best response.0So it gives me the spinners i drew and it gives me a Chart dw:1434422759820:dw

Best ResponseYou've already chosen the best response.0now we find p((1,3)) we need to all the possible pairs here

Best ResponseYou've already chosen the best response.0and it just asks what is the probability of spinning double threes

Best ResponseYou've already chosen the best response.0i 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

Best ResponseYou've already chosen the best response.0same go with (1,6)

Best ResponseYou've already chosen the best response.0or does it matter from which spinner gives 1 or 3?

Best ResponseYou've already chosen the best response.0if that matter we need to narrow that list down

Best ResponseYou've already chosen the best response.0Nope it doesn't matter. Thank you! Ill do that!

Best ResponseYou've already chosen the best response.0just 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

Best ResponseYou've already chosen the best response.0well i think it is clear now :)

Best ResponseYou've already chosen the best response.0The 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 \[\large P(doubles)=3\times\frac{1}{3}\times\frac{1}{6}\]
