Given,
In a toy shop, there is a spinning wheel for the customers. A customer can spin the wheel after buying anything from the shop.
To find,
The probability that Mr. Sharma spins the wheel, what is the probability that he gets 100% discount, If Ms.Anitha spins the wheel, what is the probability she gets no prize, If Ms. Geetha spins the wheel, what is the probability that she gets the soccer hall, What is the probability of getting a free spin.
Solution,
Total number of cases/ Exhaustive cases = 10
Number of cases when Mr. Sharma spins the wheel and he gets 100% discount = 1
Probability = favorable cases/ Total number of cases
Probability = 1/10
Number of cases when Ms. Anitha spins the wheel and gets no prize= 3
Probability= 3/10
Number of cases when Ms. Geetha spins the wheel and gets the soccer ball= 2
Probability= 2/10
Number of cases of getting a free spin =1
Probability = 1/10
Hence, In a toy shop probability that Mr. Sharma spins the wheel and gets 100% discount is 1/10, the probability that Ms.Anitha spins the wheel and gets no prize is 3/10, the probability that Ms. Geetha spins the wheel and she gets the soccer ball is 2/10 and the probability of getting a free spin is 1/10.
