    Jason has two bags with 6 tiles each. The tiles in each bag are shown below: Six squares are numbered sequentially from 1 to 6. Without looking, Jason draws a tile from the first bag and then a tile from the second bag. What is the probability of Jason drawing the tile numbered 5 from the first bag and an odd tile from the second bag? 3 over 6 4 over 6 3 over 36 4 over 36

    where on earth did you get that from? a probability is a number between zero and one it can never be 2 lets go slow

    that is clear, so lets take it one step at a time how many tiles are in bag one?

    seems unlikely, since the question says "Six squares are numbered sequentially from 1 to 6. "

    yeah i get the picture the question is "how many tiles are labelled "5"?" this is not a trick question

    ok so there is 1 labelled 5, and 6 all together what is the probability you pick the 5?

    guess my words above did not help a probability is a number between zero and one, it is never two it is the ration of the number of fives to the total number of tiles, i.e one out of six or as a fraction \[\huge \frac{1}{6}\]

    you want the probability of both of those, first is a 5 AND second is odd we have the probability of each probability of first one is \(\frac{1}{6}\) probability of second one is \(\frac{3}{6}\) take the numbers and multiply them i.e. \[\frac{1}{6}\times \frac{3}{6}\]

    that is not how you multiply fractions is it? multiply means multiply top and bottom

    the answer is \[\frac{ 3 }{6 }\]

    \[\frac{1}{6}\times \frac{3}{6}=\frac{1\times 3}{6\times 6}\]

    yes got it on planet earth we call that \[\frac{1}{12}\] but that is not one of your answer choices, so go witih \(\frac{3}{36}\)
