Two spinners are spun +
and the scores are added
together. The results are
shown in the diagram
opposite.
2
a) Write down the
probability that the || 3
score is 3
b) Write down the
probability that the
score is an even
number.
c) If the two spinners
are spun 200 times,
how many times
would you expect
the score to be 2.

Answer 1

a is 7/25

b is 14/25

c is 24

Explanation:

a) because there are 25 possible outcomes and 7 of them are 3 it is 7/25

b) using the same logic 14 possible outcomes are even

c) because the probability of it being 2 is 3/25, which can be made into ?/200 by multiplying the 25 by 8, which means we have to do the same to the 3, making it 24
