Which of the following statements is NOT true about electron configurations? Multiple Choice If an atom has only one shell, it is complete with two electrons. If an atom has two or more shells, the outer shell is complete with eight electrons. Atoms with eight electrons in the outer shell are not reactive. If an atom has two or more shells, the octet rule applies. Atoms with more than eight electrons in the outer shell react by gaining electrons.

Problem 4 (9 pts) For an experiment consisting of a sequence of independent trials, the probability of success of each trial is $p$. (a) (3 pts) If the probability of observing 3 failures before 2 successes is 0.1345662, verify that $p = 0.35$. (b) (3 pts) If there are 10 trials and $p = 0.4$, and let $X = $ number of successes, what is $V(X)$? (c) (3 pts) If $p = 0.9$, and we repeat the trials until we observe a success, what is the probability that we observed less than 3 failures?
