A student studying for a probability and statistics exam will continue to solve problems from the assigned problems until they encounter four problems the student cannot solve. The probability solves a randomly chosen problem is 85%. Let X denote the number of problems attempted. Assume that trials are independent and the probability of solving a problem remains the same. Calcu probability that it takes seven problems or more attempted until the student cannot solve four problems.
