If a = b then a + b cannot possibly equal b unless both a & b = 0, which defeats the purpose of the entire equation. If you plug in any possible value besides 0, the equation disproves itself.

the odds of rolling a certain number on a single die is 1 chance in 6 rolls. in course of a game, someone rolled 3 fives. accord

Zina [86]

Answer:

Step-by-step explanation:

The expected value is the probability times the frequency.

3 = 1/6 × n

n = 18

Note: the use of the word "odds" is very misleading here. Odds are the ratio of number of successes to number of failures:

S / F

Probability is the ratio of number of successes to number of all outcomes:

S / (S + F)

So the probability of rolling a 5 is 1/6. The odds of rolling a 5 is 1/5.

Furthermore, the word "must" is also incorrect. The player didn't have to roll 18 times. They could have rolled three times and gotten a 5 each time. Or they could have rolled 100 times. 18 is simply the most likely number of rolls needed to get three 5's.

16,625/475=35

each ticket was $35

and to make sure its correct you can always multiply the amount of 1 ticket to the amount sold

475*35=16,625
