Probabilty Scribe for October 15

Wednesday, October 15, 2008
Today we did a probability asignment from the textbook so here are the first question in its 2 parts.



3. A spinner has 2 congruent sectors couloured blue and green. The pointer is spun once, and a coin is tossed.



Find the probability of each event: a) blue and tails. First you find the TPO which is 2x2 which is 4 so the TPO is 4 so if you spin blue and flip tails its 1 FO so the percent is 25%.



b) blue or green and heads. we already know the TPO is 4 so we just have to figure out the FO blue and heads is 1 and green and heads is one so there are 2 favorable outcomes so as a percent its 50%.



Sorry for the lack of pictures my next scribe will be much better.

I choose Josh F. to be the next scribe.
