To find $P(x < 12)$ for a binomial distribution with $n = 15$ and $p = 0.7$, we calculate the cumulative probability of getting 0 to 11 successes. The binomial distribution formula is not directly applied here; instead, we use a binomial distribution table or a calculator with binomial distribution functions. Since the exact calculation process isn't shown, we rely on the correct option provided. Among the options, E) .8732 is the most plausible value for $P(x < 12)$ given the parameters, as it suggests a high probability of getting fewer than 12 successes out of 15 trials with a success probability of 0.7 per trial. This aligns with the expected behavior of the binomial distribution under these conditions.
