The range of a random variable X is {0,1...

The range of a random variable X is `{0,1,2}`. Given that `P(X=0)=3c^(3), P(X=1)=4c-10c^(2),P(X=2)=5c-1`
i) Find the value of c
ii) `P(X lt1),P(1 ltXle2)" and "P(0ltXle3)`

Text Solution

Verified by Experts

The correct Answer is:
`:.(x^(3))/((x-1)(x+2))=x-1+(1)/(3(x-1))+(8)/(3(x+2))`
