How To Solve A Probability Problem-13
I purchase the product and use it for two years without any problems.

If students can master this technique and remember the definition of probability (desired outcomes over total outcomes) the hard probability problem becomes a piece of cake. And, be sure to find us on Facebook and Google , and follow us on Twitter!

The manual states that the lifetime $T$ of the product, defined as the amount of time (in years) the product works properly until it breaks down, satisfies $$P(T \geq t)=e^, \textrm t \geq 0.$$ For example, the probability that the product lasts more than (or equal to) $2$ years is $P(T \geq 2)=e^=0.6703$.

In order to find the total number of possible outcomes, the possibilities in each slot must simply be multiplied together: 4 x 3 x 2 x 1 = 24.

This process is the same for any problem where possibilities are calculated based non repeating possibilities on discreet “slots”.

This may seem difficult to understand at first, but remember that these are the number of possibilities to choose from in each slot, so there will be one less painting to choose from in slot two because one possibility is gone.

For slot three, it is one fewer painting still, and there will be just one painting left by the time the fourth is selected.

When students, even those who consider themselves strong in math, get to the final two problems of the SAT, many begin to sweat like they are about to embark on some epic journey from which they may never return.

The hard probability problem makes students very uncomfortable, but in reality most harder math problems simply require one or two more steps than less difficult problems.
