WebCumulative probabilities for an interval are calculated by multiplying the interval survival rates up to that interval. For example, the chances of survival begin in interval one as 6/6, then are 5/6 in interval two, and 4/5 for interval three giving a cumulative survival rate (probability) in interval three of 6/6 × 5/6 × 4/5 = 0.667. how many ounces in pound of chicken
