Correct Answer - Option 4 : 35/132
Given:
There are 5 purple balls and 7 orange balls.
Formula Used:
Probability = Number of observation/Total number of observation
Calculation:
The number of purple balls is 5.
The number of orange balls is 7.
The total number of balls in the box = 5 + 7 = 12
The probability of getting purple ball = 5/12
The remaining ball = 12 - 1 = 11
The probability of getting orange ball = 7/11
The probability of getting first in purple and second is orange = 5/12 × 7/11 = 35/132
∴ The probability of getting first in purple and second is orange is 35/132.
