An appliance dealer calculated the proportion of new dishwashers sold that required various numbers of service calls to correct problems during the warranty period. The records were:
No. of service calls Relative frequency
0) 0.24 1) 0.29 2) 0.31 3) 0.04 4) 0.12
Let X be the number of service calls during the warranty period for a dishwasher. What is the probability that there will be between 1 and no more than 3 service call? (Round your answer(s) to 3 decimal places.)
