How from 60 to 100 there are there are 40 probailty A teacher decides to give a total of 100 marks for a test to two students, A and B. The teacher believes A performed better than B but doesn't know by how much. So, the teacher arbitrarily divides the 100 marks into two parts and gives the larger part to A. What is the probability that A receives at least 1.5 times the marks received by B? ( mock 3 question no 13)Solution is 40/50Although i see that solution should be 41/50 as from 60 to 100, there are 41 possibilities and from 51 to 100 , there are 50 possibilities. thus, the probability is 41/50. solution has 40/50 probability
