We want to find the probability of drawing 3 red cards from a deck of 52 cards.

We will find that the probability is P = 0.1176

Let's see how to get that probability.

We know that a standard deck of 52 cards has:

  • 26 red cards
  • 26 black cards

And we assume that all the cards have the same probability of being drawn. Then the probability of drawing a red card in the first draw is just the quotient between the number of red cards and the total number of cards, we get:

p₁ = 26/52

For the second draw, we compute the probability in the same way, but now there are 25 red cards in the deck and 51 cards in total (because one is already drawn). Then the probability in this case is:

p₂ = 25/51

Finally, for the third card, we have 24 red cards and 50 total cards, then the probability will be:

p₃ = 24/50

The joint probability (the probability of drawing the 3 red cards in the same event) is the product of the individual probabilities.

P = p₁*p₂*p₃ = (26/52)*(25/51)*(24/50) = 0.1176

Jason Aldeen bought a house for $275,000. He made a down payment of 15%. The interest rate is 4.2% for 15 years.
Tpy6a [65]

Answer:

Step-by-step explanation:

Jason's down payment= $41250

Amount he needs to borrow is

275000-41250 = $233750

Jason's monthly payment would be

248476.25/180 = $1380.42

The original cost of the house that Jason Aldeen bought is $275,000. He made a down payment of 15%. This means he paid 15% of the original cost of the house. Therefore,

Jason's down payment is 15% of $275000

= 15/100 × 275000 =0.15×275000

=$41250

Since Jason's down payment is smaller than the original cost of the house, he would need to borrow.

Amount he needs to borrow is

275000-41250 = $233750

If Jason borrows $233750 at a rate of 4.2% for 15 years

Total interest on $233750 for 15 years will be

= (233750×4.2×15) /100

= 14726250/100 = $14726.25

Total amount to be paid for 15 years will be amount borrowed + interest

=233750 + 14726.25 = $248476.25

Converting 15 years to months,

15 × 12 months = 180 months.

Jason's monthly payment would be

248476.25/180 = $1380.42
