Suppose that for a tutorial class with 50 seats, 55 students have registered. Define the random variableY as the number of students who actually show up for attending in the tutorial class. The probability mass function of Yappears in the accompanying table.

Y=y	45	46	47	48	49	50	51	52	53	54	55
P(Y=y)	0.05	0.10	0.12	0.14	0.25	0.17	0.06	0.05	0.03	0.02	0.01

What is the probability that the tutorial class will accommodate the registered students who show up?
