P(Y = y)
(Type integers or decimals. Do not round.)
b. Use random-variable notation to describe the events that Y takes on the value 6, a value less than 6, and a value of at least 6.
The event that Y takes on the value 6 can be represented as
The event that Y takes on a value less than 6 can be represented as { }
The event that Y takes on a value of at least 6 can be represented as { }.
