MONDAY, SEPTEMBER 26TH

Warm Up1. True or False: The more trials you

conduct, the further away your experimental probability will be to your theoretical probability.

2. Estimate 21.5 ÷ 4.1

1. An experiment consists of rolling a number cube to see the probability of landing on an even number. Out of 50 rolls, it landed on an even number 23 times. Give the experimental and theoretical probability

2. Defi ne OUTCOME and give an example

3. Mr. Wade made 9 three point shots, 18 two point shots, and 7 free throws. What is the probability that in tomorrows game he will make a three point shot.

4. NGMS statistics show that 5 out of every 8 6 th grade students are involved in a sport outside of school. If there are 480 students in 6 th grade, how many would you predict play sports?

Ms. Pezzino gave each of you a coin to flip 20 times. You were to record how many heads and how many tails you flipped.

Is this an example of experimental probability or

theoretical probability?

ANSWER

Experimental

Define Trial and give an example

ANSWER

A single Occurrence or observation in an

experiment. Example: When rolling a number cube, each roll
