#1 Consider a t distribution with 13 degrees of freedom. Compute P(t ≥ -1.63). Round your answer to at least three decimal places.

#2 Consider a t distribution with 12 degrees of freedom. Find the value of c such that p(-c<t<c)=0.90. Round your answer to at least three decimal places.

Please reply with a clear listing of your thoughts and efforts so far, even if you think they're wrong, so we can see where things are going sideways. Thank you! ;)
