An experiment consists of drawing one card from a bridge deck. the sample space contains 52 outcomes, one for each of the 52 cards. suppose we assign a probability of 1 52 to each of the cards. find the probability that the following happens. (a) a queen is drawn. (b) the card drawn is a king or a queen. (c) the card drawn is a heart. (d) the card drawn is a red card.

a)

b)

c)

d)

Step-by-step explanation:

Formula for probability =

The total number of cards in a deck = 52

a) Number of cards having queen =4

Then the probability that a queen is drawn =

c) Number of cards having King= 4

Then , the number of cards having a queen or king =4+4=8

Then the probability that a king or queen is drawn =

c) Number of cards having heart = 13

Then the probability that a heart is drawn =

d) Number of red cards = 26

Then the probability that a red card is drawn =

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
