Answer:
Probability that the result is a multiple of 4 or a multiple of 3= 0.428
Step-by-step explanation:
The spinner is divided into 14 equal areas.
Probability of an event=
For favourable events,result should be a multiple of 3 or 4.
All the possible outcomes are=1,2,3,4,5,6,7,8,9,10,11,12,13,14
- Multiples of 3=3,6,9,12
- Multiples of 4=4,8,12
Hence the favourable outcomes are=3,4,6,8,9,12
Number of favourable outcomes=6
Total number of outcomes=14
Probability=
=0.428
