A card is selected at random from a well-shuffled ordinary deck consisting of 13 spades, 13 clubs, 13 hearts, and 13 diamonds. 4
Elis [28]

Answer:

b) 0.42

Step-by-step explanation:

Let A be the event that card is a heart card and B be the event that card is a face card.

We have to find P(A or B). P(A∪B)=?

P(A∪B)=P(A)+P(B)-P(A∩B)

There are 13 heart cards and  12 cards are face cards. There would be 3 face card in hearts. So,

P(A)=13/52=1/4=0.25

P(B)=12/52=3/13=0.231

P(A∩B)=3/52=0.058

P(A∪B)=0.25+0.231-0.058

P(A∪B)=0.481-0.058

P(A∪B)=0.423

So, the probability that the card is a heart or is a face card is about is 0.42.

Bill plans to buy school supplies and the following equation represents what he bought.
iren2701 [21]

Answer:

1. x = 8

2. y = 1/2

Step-by-step explanation:

1. Plug the function

5x + 20(0.50) = 50

= 5x + 10 = 50

Subtract 10 from both side

= 5x = 40

Divide 5 on both sides

= x = 8

2. Plug in the function

5(8) + 20y = 50

= 40 + 20y = 50

Subtract 40 on both sides

= 20y = 10

Divide 20 both sides

= y = 10/20 | 1/2
