In a million years, I never would have thought that a spousal argument would occur over a calculator.  Not just any calculator, but a TI-84 Plus…

Unfortunately we only have one — which cost something akin to buying a large appliance.  I’ve been using it for my university statistical Math course; getting quite comfortable calculating t and z distributions of many sample proportions.  Now with a month left (read: crunch study time), hubby comes along with his condensed Math 12 summer course and I’m sitting here with my unsolved binomial distributions.  How will I ever know the probability of rolling a die 1000 times that it will roll a 6 fewer than 160 times?

Since we are on the same study/school/work schedule, we’ll have no choice but to purchase another, not a very sound investment, seeing as how both courses end Aug 7th and I’ll probably never touch a calculator again — unless I’m trying to figure out a tip (yes, my math is *that* good!)  Now give me back my calculator!!!!

(In case you were wondering, there is a 28% chance of rolling a six fewer than 160 times.)
