Question

6. You spin a spinner that has eight equal-sized sections numbered one to eight. Find P(perfect square or odd).

Answer 1

perfect squares from 1 to 8 are 1,4
The odd numbers are 1,3,7,5

P(perfect square or odd)
= P(1, 3, 4, 5 or 7)
= P(1) + P(3) + P(4) + P(5) + P(7)
= 1/8 + 1/8 + 1/8 + 1/8 + 1/8
= 5/8

Answer 2

perfect square or odd
=1-P(not square nor odd)
=1-(P(2)+P(6+P(7)
=1-(1/8+1/8+1/8)
=1-3/8
=5/8

Answer 3

@UnkleRhaukus
1-(p(2)+p(6)+p(8))

Answer 4

Favourable cases ={1,3,4,5,7}
P=5/8

Answer 5

yeah @lalaly, that is what i ment on line 2
