Best ResponseYou've already chosen the best response.5well we know there is a gap of 2 hours when the delivery van can come that is the same as 120 minutes we also know that out of that 120 minutes, 20 minutes the doors will be locked so we minus this from the total hours it is open 120  20 = 100 this means out of 120 minutes there is 100 minutes where the doors will be open which gives us the probability 100/120 after simplifying this you will get the answer 5/6 dont forget to click best response =)
