Question:
At a birthday party, the children spin a wheel to get a gift.
Find the probability of
(a) getting a ball
(b) getting a toy car
(c) getting any toy except a chocolate.
Solution:
(a) The probability of getting a ball
$=\frac{\text { Number of events of getting a ball }}{\text { Total number of events }}=\frac{2}{8}=\frac{1}{4}$
(b) The probability of getting a toy car
$=\frac{\text { Number of events of getting a toy car }}{\text { Total number of events }}=\frac{3}{8}$
(c) The probability of getting any gift except a chocolate
$=\frac{\text { Number of events of getting any gift except a chocolate }}{\text { Total number of events }}=\frac{7}{8}$
