Probability line scissors, glue pen,
RM 87
A probability line can be used to show how likely an event is to happen.
It is always numbered from 0 to 1.
Q-* —— less and less likely to happen ___ 1 __ more and more likely to happen — ^ -|
I 1 1
impossible even chance certain
Work with a friend if you like.
Cut out the 12 statement cards on RM87.
On a long strip of paper, make a probability number line
like the one shown below.
Decide where on the scale is the most sensible place to put the statements.
We've put this statement
very near 0 because
can glue the cards down it's very unlikely to happen.
and draw lines to where you
think they best /it on the line.
even chance
CHALLENGE
Make cards to put at these positions on the scale.
