An experiment consists of ranomly drawing three cards in succession without replacement from a standard deck of 52 cards. Let A
nadya68 [22]

Answer:

0.0045248 ;

0.1312218 ;

0.0001809 ;

0.1659729

Step-by-step explanation:

Number of Kings in deck = 4

Total number of cards in deck = 52

Picking without replacement :

A = King on first draw :

P(A) = 4 / 52

A = King on 2nd draw :

P(B) = 3 / 51

A = King on 3rd draw :

P(C) = 2 / 50

1.) P(A n B) = P(A) * P(B)

P(A n B) = 4/52 * 3/51 = 12 / 2652 = 0.0045248

2.) P(A u B) = P(A) + P(B) - P(AnB)

P(AuB) = 4/52 + 3/51 - 0.0045248 = 0.1312218

3.) P(A ∩ B ∩ C) = P(A) * P(B) * P(C)

P(A ∩ B ∩ C) = 4/52 * 3/51 * 2/50 = 0.0001809

4.) P(A U B U C) =

P(A) + P(B) + P(C) - P(AnB) - P(AnC) - P(BnC) - P(AnBnC)

P(AnC) = P(A) * P(C) = 4/52 * 2/50 = 0.0030769

P(BnC) = P(B) * P(C) = 3/51 * 2/50 = 0.0023529

4/52 + 3/51 + 2/50 - 0.0045248 - 0.0030769 - 0.0023529 + 0.0001809 = 0.1659729

Suppose that 2 people exercising in an enclosed room are each generating about 2.400 BTUs of body heat per
noname [10]

Answer:

0.002  BTUs per cubic foot heat is produced per hour

Step-by-step explanation:

Given:

Number of person = 2

Amount of heat produced by one person = 2.400 BTU

Dimension of the room = 20 ft x 12 ft x 10 ft

To Find:

How many BTUs per cubic foot do they produce in 1 hour = ?

Solution:

E =\frac{ \text{(2400 Btu/ person hr}) (\text{Number of Hours}) (\text{Number of persons }) }{\text {volume of the room}}

Substituting the values

E = \frac{ \text{(2400 Btu/ person hr}) (1) ( 2) }{20 ft \times 12 ft \times 10 ft}

E = \frac{4.800}{2400}

E = 0.002  BTU per cubic feet
