Answer:

$\text{P(red or blue)}=(3)/(4)\\\\\text{P(not purple)}=1$

Explanation:

3. From the given spinner, the number of red sections = 3

Number of blue sections= 3

Then, the number of sections which are red or bl;ue = 3+3=6

Total sections=8

Then ,

$\text{P(red or blue)}=\frac{\text{Number of sections which are red or blue}}{\text{Total}}\\\\\Rightarrow\text{P(red or blue)}=(6)/(8)=(3)/(4)$

4. From the given spinner, the number of purple sections =0

Total sections= 8

Number of sections which are not purple =8

Now,
$\text{P(not purple)}=\frac{\text{Number of sections which are not purple}}{\text{Total sections}}\\\\\Rightarrow\text{P(not purple)}=(8)/(8)=1$
