Year 4 Maths - Probability

The learning just never stops in the Realm of Rodda! We have been hard at work in maths learning about probability. Probability is the chance that something will happen - how likely it is that some event will happen.

Sometimes you can measure a probability with a number like "10% chance of rain", or you can use words such as impossible, unlikely, possible, even chance, likely and certain.

Example: "It is unlikely to rain tomorrow".

One of our learning activities was to toss a coin as many times as we could in 2 minutes and to record in a tally, how many times we tossed heads or tails. We then discussed what sort of chance we had of getting either heads or tails each time we tossed the coin. Finally, we investigated the probability of different events occuring.

If i tossed a coin 50 times how many times will heads come up?

Based on probability I have a 1 in 2 chance on getting heads each time I toss the coin, so the probability is that I will toss 25 heads. Remember though that probability is just a guid.

Get tossing and let us know in the comments how many heads and tails you tossed!

  1. I had more tails than i did heads. Do you know why that is?
