Answer 1

the first one is 3/4

second one is 1 not sure on the second one tho

Answer 2

`\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`
