Odds calculation

[Tasha]

I need some help with this, basic though it is.

If the probability of something happening is 7/10 does that make the odds of it happening 7/3?

[Keith]

if the chance of something happening is 7/10 then it will happen on average 7times and not happen 3 times for every 10 attempts

7:3, yes - but, more importantly, why do you need to know this?

[NightGizmo]

Some write the odds as 7:3, others as 70%. They mean the same thing, but the 7:3 notation makes it easy to compare against money odds. If you bet $7 to win $3 in a 7:3 situation, you would break even statistically. If you could bet less or win more, it's a +EV situation.

Basically, Take a pack of cards.

Q) 52 cards in the pack , the probability of you pulling any Ace out is ?

A) There are 4 aces , so 4/52 is the fraction , which simplifies to 1/13.

Do you know that 4/52 is the same as 1/13 ?

If you do , you should see that 7/10 cant be 7/3
