A new nurse has a chance of successfully starting an IV 0.69 of the time it tries. The nurse has reviewed her textbook on starting IV properly and is now ready to attempt two successful IVs in a row. The probability that a nurse starts second IV successfully given it successfully started the first IV is 0.89. Let: A = the event nurse is successful on first attempt; P(A) = 0.69. B = the event nurse is successful on second attempt; P(B) = 0.62. What is the probability that the nurse successfully starts first IV or the second IV? Your
