Answer 1

the first one is 3/4

second one is 1 not sure on the second one tho

Answer 2

Answer:

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

Step-by-step 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 ,

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

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

Total sections= 8

Number of sections which are not purple =8

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