Representation of a binary communication channel

how do I do this?

using x=rand(1,10000)<0.5

generate a vector that represents an input sequence of 0s and 1s. 

Simulate the channel by writing code to do the following:
• For a 0 in the input sequence, the code should generate an output of 0
with probability .95 and an output of 1 with probability .05
• For a 1 in the input sequence, the code should generate an output of 1
with probability .90 and an output of 0 with probability .10.
