Below is a chart of John Legend songs and the age groups who liked these songs with the data values. ORDINARY PEOPLE OF ME 125 205 122 201 63 25 100 AGE GROUP210 278 321 ABOVE Find P( age group was between 21--30) - Express answer as unreduced fraction!!! A box has four balls in it; one white and 3 black Find the probability that the ball you selected at random (blind draw) is white ball LEAVE ANSWER AS AN UNREDUCED FRACTION On the flight from Rome to New York, Mona, the flight attendant wheeled her cart which contained 16 cans of Pepsi, 24 cans of Coke and 18 cans of iced tea. A passenger asked her to 19 give him a can at random; find the probability that the can is a not ANICE TEA? Leave answer as an unreduced fraction. 20 If the weather prediction service showed these two scenarios where the clouds are predictors of rainfall, which scenario or 2) shows a greater probability of rain a. Map 1 b. Map 2 c. Both show the same d. None of these answers The probability that on Monday, a viewer will watch an episode othe show Blacklist is 29,06%. 1.300.000 21 people watched Blacklist last Monday. What is the probability that a viewer WILL NOT watch an episode of Blacklist on Monday 7 Express your answer as a percent to 2 decimal places

Explanation / Answer

Problem No.17

n= total number of individuals = 988

number of individuals between age group between 21-30 =278

P( age group was between 21-30) = 278/988 = 139 / 494

Problem No .18

n = total number of balls = 4

number of white balls = 1

P( Selected ball is white) =1/4

Problem No.19

n= total number of cans = 58

number of cans of ice tea = 18 58

P( can is an ice tea) = 18/58

Since the total probability is one

Hence

P( Can is not an ICE tea) = 1 - 18/58 = 40/58 = 20/29

P( Can is not an ICE tea) =20/29

Problem No. 20

n = total number clouds = 12

n1= number of clouds in map 1 = 8

P(Map 1 Predicts the rain ) = 8/12 =2/3

n2 = number of clouds in map 2 = 4

P(Map 2 predicts the rain ) = 4/12 = 1/3

Since P(Map 1 Predicts the rain ) > (Map 2 predicts the rain )

Hence Map 1 shows greater probability of rain.

Problem No .21

Given that

The probability that on Monday a viewer will watch an episode of the show blacklist is 29.06% = 0.2906

Since the total probability is one

Hence

The probability that on Monday a viewer will not watch an episode of the show blacklist is = 1-0.2906 = 0.7094 = 70.94%
