4) You are in Las Vegas and need $35 to buy a great steak dinner, but you only have $20. You decide to play roulette to win the

Answer:

The probability that you will have $35 after your bet is 0.5263

Step-by-step explanation:

Consider the provided information.

If you bet $1 on each of 20 different numbers on one single spin of the wheel, what is the probability that you will have $35 after your bet.

If you bet $1 on a single number then the probability of winning is:

$\frac{1}{38}$

But if you bet $1 on each of 20 different number then the probability increases.

Thus the required probability is: $\frac{20}{38}\approx0.5263$

Hence, the probability that you will have $35 after your bet is 0.5263

If Janet scored an 85% on her test she answered 34 questions correctly how many questions were on the test

Wittaler [7]

40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.
