How to solve a fraction without simplifying it in a ti-84

[serene slate]

Hmm

I don't know probability but

You just see if have common factors

Like in a cross way

You just list common factors of them

And get greatest one

And divide it

By that greatest

You can also just take your final result and multiply it by 52 on the calculator

This gives the numerator if the denominator is supposed to be out of 52

If x=y/52, then y=52x

He doesn't want to use calculator

He explicitly wants to do it with a calculator if I'm reading the question correctly

Also looking back at the question 26/52 *4/52 is not the correct way to approach this probability wise

This is just a fluke for the most part from this specific problem

There are 4 kings and half of them are red

So there are 2 red kings

But there would be no way to get P(red and king) from P(red) and P(king) without having more knowledge about the structure of the deck

You don't compute 2/52 in this problem at all

This just needs you to know the card composition of a deck of cards

[desert void]

Exactly, you just have to know that there are 2 red kings in a deck!
@plain hill They are not multiplying the fractions!
