Bob is running late for his class and missed his bus. he calls his friend sam to ask for a ride to school. sam, tired of bob interrupting his sleep every week, has lowered the volume of his phone. there is a 70% chance sam sleeps through bob's phone call and does not answer this morning. if sam answers the phone, he will drive to bob's house and give bob a ride. bob will get to school in x minutes, where x follows a (continuous) uniform(15,25) distribution. if sam does not answer the phone, bob has to walk to school. bob is a consistent walker, and will always make it to school in exactly 40 minutes. what is the expected time for bob to get to school today (in minutes)?
