Scribe Post, March 4, 2009

Today in Math, we did Number Of The Day, as usual. The Number of the Day is 7791.692. We also continue doing Probability.

Probability continued

Outcome means one possible result of a probability experiment.

Favourable outcome means a succesful result in a probability experiment.

Examples:

The tiles S, N, O, and W are placed in a bag. What is the probability of drawing a letter W from the bag?
Another way to write this question is P(W).

1. P(W) = favourable outcomes
over
possible outcomes

P(W) = 1/4

If they ask you in a sentence you must answer in a sentene too.
The probability of drawing a W is 1/4, 25%, or 1:4.

2. P(S or O) = favourable outcomes
over
possible outcomes

P(S or O) = 2/4

You always need to simplify your answer.

P(S or O)= 1/2

P(S or O) =1/2, 25%, or 1:2

Homework:

The letters M, O, U, N, T, A, I, N are in a bag.


A. Probability of drawing a letter N

B. P(consenants)

C. P(letter)




I pick Charlie to do the next scribe post.
