Question

We started working on probability and I am having a hard time understanding how to do odds

Answer 1

The odds in favor = success/ fail = 3 : 8

Answer 2

I thought so, I have a few more problems do you think you could help me?

Answer 3

Just post all up. There's so many talented helpers around you!

Answer 4

Thank you

Answer 5

If the probability an event will occur is 1/2 determine
A) the probability that the event will fail
B) the odds against the event occuring
C) the odds in favor of the event occuring

Answer 6

P(s) + P(f) = 1

.5 + P(f) = 1 ; when P(f) = .5

Answer 7

in any given event; the probability associated with 1/2 is if there is a 1 to 1 ration of successes and failures; so the odds would be 1:1

Answer 8

ok so is that the ans for all 3 problems or just A
Thank you so much

Answer 9

The key is the terms:
P (Pass + Fail) = P(occur + not occur) = P(against + favor) = 1

Answer 10

I understand the equation what I am having a hard time with is know where to place the values

Answer 11

a card is chosen from a standard deck of cards determine the odds for and against
picking a heart

Answer 12

P ( agaisnt heart) = number card of not heart/ number card of heart

Answer 13

13 hearts total

=> 52 - 13 = 39 cards not heart
Thus P (against heart) = 39 : 13
