A certain spinner has equally sized slices. The probability of landing on a red slice is 4/9. What are the odds in favor of land
Novosadov [1.4K]
There are 4 red slices out of 9 total. So there are 9-4 = 5 slices that are not red. The odds in favor of landing on red is 4:5

We basically write the number of ways to get what we want (4), followed by a colon, then the second number is the number of ways to get what we don't want (anything but red; 5 ways)

So that's why the answer is 4:5

-----------------------------------

Side Note -- If we want the odds against, we simply flip the ratio. The odds against would be 5:4 because there are 5 ways to lose and 4 ways to win. This is assuming that landing on red means you win.

Elba has a quarter, a dime, and a nickel. If tails comes up at least twice, Steve wins. Otherwise Elba wins. Find probability (E
N76 [4]

Hi there!

The easiest way to think about this is what cases Elba will win. We know that Steve will win if tails comes up at least twice. He will lose if tails comes up only once or 0 times. This means that heads will either come up twice or 3 times, meaning Elba will win <u>if tails comes up at least twice.</u>

Thus, looking at this, we can see (as heads and tails is a 50 50 chance) that the probability is the same because the <u>situation in which they win is the same, but flipped</u> (from heads and tails).

Thus, this means that Elba wins 1/2 of the time.

Hope this helps! Feel free to let me know if you have any questions about this specific question.
