Day 3

Daily Objective- "Students will be able to find the number of outcomes for compound events, identify independent and conditional events, and compute probability and odds."

This shows probability, and how to find outcomes

• Finding probability doesn't have to be as complicated as everyone makes it out to be. You have a spinner (Circular) cut into 4 pieces evenly. Each section equals 25% of the circle, so the probability of the spinner landing on each piece is 1/4. 

Quiz

1. John has 3 blue t-shirts, 3 green t-shirts, and 7 black t-shirts in his closet. What is the probability of John getting a blue shirt? 
2. If John rolls a number di, what is his chances of getting a 5?
3. If John rolls a pair of dice, what is probability of him getting an even number? 

Answer Key

1. 3/11 or 27% of the time. (3+3+7=11. 3/11=.27) 
2. 1/6 or 17% of the time. (6 sided dice, 1/6=.1666666)
3. 1/2 or 50% of the time. (6 sided dice x2=12 total sides.)
