R1: Identify the mystery spinner: a mystery spinner is spun 100 times and the results recorded. Identify the mystery spinner from the results.

R2: Coins tossing simulation: Toss up to four coins up to 100 times.

 

 

R3: Spinner simulation (see picture): points are plotted to show the relative frequency of each score against the number of trials. First use the slider to determine the number of trials then play the simulation. The simulation can be started and stopped.

R4: One coin tossing simulation: one coin is tossed and points are plotted to show the relative frequency of heads against the number of trials. First use the slider to determine the number of trials then play the simulation. The simulation can be started and stopped.

To speed up the simulations press the space bar.

A bee collects pollen: probability simulation

A bee starts in the centre of the grid (see picture) and moves along the lines of a grid of flowers. The bee moves from one flower to the next - up to 5 moves. It will then land on a flower.
At each flower the bee moves north, south, east or west. It is equally likely to move in any of the four directions.
What is the probability it will land on any particular flower?
The first bee simulation will generate random results. First decide how many moves the bee will make and how many trials to run. The simulaltions can be run at two speeds: slow or fast, click on the slow/fast button.
The second bee simulation will generate the expected results.

R5: Bee simulation 1 (random results)

R6: Bee simulation 2 (expected results)

Simulation 1 could be used to introduce the activity. The pupils could then have a go at working out the probabilities on paper.

Tree Diagrams
Coins
Toss either 2, 3 or 4 coins up to 500 times. Watch the tree diagram and bar chart display the outcomes.
First select how many coins you want and the number of trials then click the 'play' button.
Use the buttons below to start and stop the simulation.

R7: Coins tree diagram

Two Dice
Roll two dice up to 500 times, add together the scores. The speed can be either slow or fast: click on the slow/fast button.

R8: Two dice tree diagram
R9: Two dice expected results: the dice are rolled 36 times giving the expected results.

R10: Dice... same but different
If you are using Internet Explorer press F11 to view the resource full-screen.
If two dice are rolled there is one way to score 2, two ways to score 3....one way to score 12.
Find another pair of non-standard dice that give the same number of ways of obtaining the same sums.
There must be at least one dot on each face.

Use this simulation to choose the number of dots on each face of the dice. The simulation will play all the possible outcomes.
To choose the numbers on the dice: click on the face of a blue or red dice then click on a number button.
Change the speed of the simulation by clicking the slow/ fast button.

R11: Match the spinner with the frequency table. Eight spinners are spun 100 times and the results recorded in tables. Which spinner goes with which table? Click underneath the spinners to reveal the answers.

R12: Match the spinner with the graph. Eight spinners are spun 100 times and graphs are generated. Which spinner goes with which graph?

 

 

R13: Spinners game
A game is played by spinning each spinner once. To win a prize the two spinners must stop at the same letter. Work out the probability both spinners wil stop at the same letter and how much is won or lost in a game. Click underneath the spinners to reveal the answer.
