Probability is about estimating how likely (probable) something is to happen. Probability can be used to predict, for example, the outcome when throwing a die or tossing a coin.
We often use words to describe how probable we think it is that an event will take place. For example, we might say that it is likely to be sunny tomorrow, or that it is unlikely to snow in August.
Have a look at the statements below, and decide whether the following events are: certain, likely, very likely, evens (neither likely or unlikely), unlikely, very unlikely or impossible.
A game is played where 7 beads with digits from 1 to 7 on them are placed in a bag, a bead is taken out, and you then have to guess whether the number on the next one to be taken out will be higher or lower, and so on.
In each case, choose an appropriate word from the following list to complete each sentence:
Remember that there is only one of each number.
If the 1st bead is 7, what is the chance of the 2nd bead being lower than 7?
If the 2nd bead is 1, what is the chance of the 3rd bead being lower than 2?
If the 3rd bead is 6, what is the chance of the next bead being higher than 4?
