People per Household

In the 2001 population census, information was collected about the number of people in each household, which is denoted by \(X\). It is given that \(P(X=1) = 0.25\), \(P(X=2) = 0.32\), \(P(X=3) = 0.18\), \(P(X=4) = 0.15\), \(P(X=5) = 0.07\), \(P(X=6) = 0.02\) and \(P(X\geq 7) = 0.01\). If \(R\) is the probability that there are at most \(4\) people in the household, what is the value of \(100R\)?
