Class 9Probability from DataStatistics
  • A(Number of trials in which E happened) / (Total number of trials)
  • B(Total number of trials) / (Number of trials in which E happened)
  • C(Number of trials in which E happened) (Total number of trials)
  • D(Total number of trials) - (Number of trials in which E happened)

Step-by-Step Solution
