How Likely is it?

Maria is flipping a coin and spinning a spinner. The spinner has 4 equal sections labeled A-D. What is the probability the coin will land on heads and the spinner will land on the letter "A"? (Hint:  make a list of outcomes before finding probability)

1/8 or 0.125, or 12.5%

Hasaan has a spinner with 5 equal sections, each a different color. After only 10 spins, the pointer had landed on red 40% of the time. After a whopping 1,000 spins, the pointer landed on red only 22% of the time. How can Hasaan account for this change in experimental probability?
As the number of trials increase, the experimental probability reaches closer to the theoretical probability. (The Law of Large Numbers)
100

What is the difference between experimental and theoretical probability.

Experimental is based on results and theoretical is based on what should happen


100

Define "theoretical probability."

It is the probability of what should occur.

100

How likely is it that a coin is flipped and lands on tails?

Equally likely

The classic wood carousel at Carousel Park in Hampton, VA has 32 jumping horses and 16 standing horses. What is the probability of randomly selecting a jumping horse?

1/2, or 0.50, or 50%

You throw a dart at the dart board with the following results:  1-blue   3-red  4--wall.  What is the probability that your next dart will hit the wall?

1/2

200

What is the number of possible outcomes for spinning one spinner with 8 equal sections and another spinner with 6 equal sections?

48 possible outcomes

200

Define "experimental probability."

The probability of what actually occurs.

How likely is it that a number cube is tossed and lands on 3?

Unlikely

300

What is the probability of rolling an odd number or a 2 with a standard number cube?

2/3, or 0.67, or 67%

300

A letter tile is randomly selected from a bag, recorded, and replaced 100 times. The results are listed below. What is the experimental probability of selecting the letter "E"? A = 16 E = 11 I = 29 O = 19 U = 25

11/100 or 0.11, or 11%

300

What are the outcomes for a 10 sided di?

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

300

Describe the difference between events that are certain, likely, equally likely, unlikely, or never going to happen.

Certain would be 100% of the time, likely is anything greater than 50% of the time, equally likely is exactly 50% of the time, unlikely is anything less than 50% of the time, and never is anything that has a 0% chance of occuring.

300

How likely is it that a number cube is tossed and it lands on 8?

never going to happen

400

There are 3 red marbles, 2 green marbles, and 1 yellow marble in a box. What is the probability that the marble taken out was red or green.

5/6, or 0.83, or 83%

Pedro recorded the types of birds that visit his bird feeder. Based on the results below, what is the probability the next bird will be a chickadee? Woodpecker = 3 Chickadee = 5 Cardinal = 1 Sparrow = 13 Blue Jay = 3

1/5, or 0.20, or 20%

Jarvonya spins a spinner with 5 equal sections numbered 1-5 and she spins another spinner with 5 equal sections with the letters A-E. What is the probability she will spin a 4 and a B? (Hint:  make a list of outcomes before finding probability)

1/25 or 0.04, or 4%

500
A six-sided die is thrown 50 times. Using the list below, how does the theoretical probability of rolling a 3 compare to the experimental probability of rolling a 3? Number on Die How Many Times it Landed on that Number 1 8 2 6 3 7 4 12 5 10 6 7
The theoretical probability is higher than the experimental probability. (Theoretical = 17%, Experimental = 14%)
