Suppose the probability of winning four persons say X$,$ Y$,$ Z and W in a hurdle race is P$($X$)=0\mathrm{.}25,$ P$($Y$)=0\mathrm{.}25,$ P$($Z$)=0\mathrm{.}35,$ P$($W$)=0\mathrm{.}15.$ But on eleventh hour the player Z decided to not participate in a race and withdraws. Then find the new probabilities of X$,$ Y and W$$s winning.
