- Determine the probability of a “favorable” even occurring

Probability, Events and Outcomes

Yoyoyo welcome back!!!!!!!! Happy NEW YEAR!

Ex: …. In the problem above, the experiment is spinning the spinner. Do you agree?!

The possible outcomes are landing on orange, blue, green or red.

One event of this experiment is landing on blue.

The probability of landing on blue is one-fourth.

To land on BLUE would be a “favorable” outcome for me.

- Probability Of An Event P(A) =

What’s the probability of landing on yellow?

Red?

- A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?
- What are the possible outcomes?....
