Lewis rolls a number cube and then chooses a card from a set of cards numbered 1 through 5. What is the probability that he will
IceJOKER [234]

Answer:

\frac{1}{5}=0.2

Step-by-step explanation:

The general formula for a probability is:

P=\frac{FavorableEvent}{TotalEvents}

The favorable events for the cube to fall in a even number are:

2, 4, and 6 ⇒ <u>3 favorable events</u>

and in the cube the total events are:

1, 2, 3, 4, 5, 6 ⇒ <u>6 total events</u>

So the probability of rolling an even number in the cube is:

P=\frac{3}{6}\\\\\\ P=\frac{1}{2}

Now we do something similar to find the probability to choose a card with an even number.

The favorable events for an even numbered card are:

2, 4 ⇒<u> 2 favorable events</u>

and the total number of events in the cards is:

1, 2, 3, 4, 5 ⇒ <u>5 total events</u>

Thus, the probability to choose an even numbered card (according to the probability formula) is:

P=\frac{2}{5}

And finally, since we want both things to happen we must multiply both obtained probabilities:

  • the probability that he will roll an even number and choose an even numbered card:

P=\frac{1}{2}*\frac{2}{5} \\ \\P=\frac{2}{10} \\\\P=\frac{1}{5} =0.2

The probability is 1/5 which is equal to 0.2 or 20%

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day.
VladimirAG [237]

Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.

Step-by-step explanation:

Today, Lin's sister's balance is -$2.67

She gets charged $5.95 per day.

There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times

So her balance after 14 days will be:

Balance = -$2.67 - $5.95*14 = -$85.97

When she charges the $430 in the account, her balance will be:

Balance = -$85.97 + $430 = $344.03

So now she has a positive balance, which means that the bank does not charge her anymore.

Answer:

24/5 (4.8)

Step-by-step explanation:

5:8 = 3:x

Divide both sides by 3

That means 24/5 = x
