The spinner at the right is spun once. Find the probability of each event. Write each answer as a fraction, percent, and decimal

b = 1/10, which equals to 10% and .1
c = 2/10, which simplified to 1/5, which equals 20% and .2
d = 3/10, which equals 30% and .3

this is because, with probability, you ‘divide’ the amount of something you want to get with how many possible outcomes there are. so for this question, there were 10 possible outcomes. so then i ‘divided’ the number of outcomes i wanted, which were 1,2, and 3 respectively, and that’s how i came out with those answers.
