True or False, Drawing a Jack from a deck of cards, not replacing it, and then drawing a king are examples of dependent events

1 answer:

3 0

Answer: The probability of drawing a king from the deck has been changed when a Jack is drawn and not replaced back. So the two events are dependent. The answer to this question is TRUE

Step-by-step explanation:

Two events are dependent if the occurrence of one event affects the probability of occurrence of the other event.

Total number of cards in a deck are 52. There are 4 jacks and 4 kings.

If we simply pick up a king from the deck, the probability of picking a king would be

However, when a Jack is drawn from the deck of cards and not replaced back, the number of total cards reduces by 1. So now the total number of cards in the deck is 51 with 4 kings. In this case the probability of drawing a king is 4/51

Ive tried everything and still dont understand can you help?

vredina [299]

Answer:

13.896 kg

Step-by-step explanation:

Volume of Gold Bar = Area of [Trapezium x Length of Bar]

Length of Bar = 16 cm

Area of Trapezium = 2 × Area of Triangle + Area of Rectangle

Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²

2 × Area of Triangle = 2 × 7.5 = 15 cm²

Area of Rectangle = 6 × 5 = 30 cm²

Area of Trapezium = 15 + 30 = 45 cm²

Volume of Gold Bar = 45 × 16 = 720 cm³

Density of Gold = 19.3 g/cm³

Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg

Mass of Gold Bar = 13.896 kg

Therefore the mass of the Gold Bar is: 13.896 kg (kilograms).

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 pe

tamaranim1 [39]

Answer:

$13,400

Step-by-step explanation:

Given the following data;

Tuition and book per year = $5,500

Transportation per month = $100

In 2 years;

Total tuition and book = $5,500 * 2 = $11,000

Total tuition and book cost = $11,000

Transportation;

There are 12 months in a year, in 2 years = 12 * 2 = 24 months.

Thus, total on transportation = $100 * 24 = $2,400

Total transportation cost = $2,400

$Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost$

Substituting into the above equation, we have;

Overall cost = $11,000 + $2,400

Overall cost = $13,400.

Hence, Lakita's education will cost her $13,400 in total.
