Transactions to a computer database are either new items or changes to previous items. The addition of an item can be completed less than 100 milliseconds 94% of the time, but only 20% of changes to a previous item can be completed in less than this time. If 30% of transactions are changes, what is the probability that a transaction can be completed in less than 100 milliseconds? Round your answer to two decimal places (e. g. 98.76).
