Answer:

B is the answer

Step-by-step explanation:

A = πr²

24π = πr²

24 = r²

24 = r²

\sqrt{24} = r

r = \sqrt{4}\sqrt{6} = 2\sqrt{6}

C = 2πr

C = 2π(2\sqrt{6})

C = 4\sqrt{6}π

An advertising campaign is canceled before launch with probability 0.10, in which case the marketing company is fired with proba
Feliz [49]

Answer:

0.2231 (22.31%)

Step-by-step explanation:

defining the event F = the marketing company is fired, then the probability of being fired is:

P(F)= probability that the advertising campaign is cancelled before lunch * probability that marking department is fired given that the advertising campaign was cancelled before lunch + probability that the advertising campaign is launched but cancelled early  * probability that marking department is fired given that the advertising campaign is launched but cancelled early        ....   (for all the 4 posible scenarios where the marketing department is fired)

thus

P(F) =0.10 * 0.74 + 0.18 * 0.43 + 0.43 * 0.16 + 0.29*0.01 = 0.2231 (22.31%)

then the probability that the marketing department is fired is  0.2231 (22.31%)
