Hint: Use the conditional hazard rate functions to calculate cooditional survival funethons, asd thes calculate the unconditional survival function as a welghted sum of survival functions because of the property of micture model/law of total probalility. You cannot calculate the unconditional hazard rate function using the weighted sum of conditional hazard rate functioes since they are not probabilities).
