The probability that the marble will be in one of the first three slices of the cake will be 31.8% so option (C) will be correct.
What is probability?
The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts and like that.
Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
Given that dia of cake = 9 inches
Perimetere of cake = πD = 9 ×22/7 = 28.29 inches.
The perimeter of 3 slices of a piece with an arc length of 3 inches,
3(3) = 9 inches.
Probability of having marble in the first 3 piece
(9/28.29)100 = 31.81 %
Hence, it is clear that the probability that the marble will be in one of the first three slices of the cake will be 31.81 %.
