3. The cumulative distribution function (CDF), of a particular brand of flash drive is Fr(t) 0 for t s5.0, Fr(t) (t-5.0) for 5.0<ts6.0, and Fr(t) 1 for t> 6.0. Here, time t has the units of years. a. Sketch Fr(t) versus t. Show proper axis labels, scales, and units. b. Express mathematically reliability RT(t) versus t for t2 0, and sketch it below Fr(t) to the same horizontal scale. Show proper axis labels, scales, and units. Express mathematically probability density...
