ii. If Ms.Anitha spins the wheel, what is the probability she gets no prize?
iii. If Ms. Geetha spins the wheel, what is the probability that she gets the soccer hall
iv. What is the probability of getting a free spin?
Answers
Answer:
Total no, of possibilities =8,
(i)
No of events of getting a ball =2
Probability=
Total no of events
No of events of getting a ball
=
8
2
(ii)
No of events of getting a toy car =3
Probability=
Total no of events
No of events of getting a car
=
8
3
(iii)
There is only one event of getting chocolate
So, No. of events of getting any toy except chocolate =8−1=7
Probability=
Total no of events
No of events of getting other toy than chocolate
=
8

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:
Observe the given figure and answer the given questions.
Solution:
According to the formula,
Probability = The number of favorable outcomes / The total number of outcomes
By observing the figure,
The total number of outcomes = 10
(i). Mr. Sharma spins the wheel,
The probability that he gets 100% discount = 1 / 10 = 0.1.
(ii). Ms. Anitha spins the wheel,
The probability she gets no prize = 3 / 10 = 0.3.
(iii). Ms. Geetha spins the wheel,
The probability that she gets the soccer ball = 2 / 10 = 0.2.
(iv). The probability of getting a free spin = 1 / 10 = 0.1.
(v). The probability that a customer wins 15% discount = 2 / 10 = 0.2.
