Answer 1

3/8 & 1/4 are the probability of  A &  B resting on table respectively

Step-by-step explanation:

A spinner is made from a regular octagon

Octagon has 8 sides

labelled with

3 A

2 B

3 C

Each of the sides is equally likely to be resting on the table when it stops spinning

probability that A resting on the table   = Number of A's/Total Sides

= 3/8

probability that B resting on the table   = Number of B's/Total Sides

= 2/8

= 1/4
