Answer 1

Given, P winning a prize) =p=0.20 Number of days =n=6 Let yn Binomial (n=6, P=0.20) pix=x) = neze pH11-P) nagl 13=0,,.. Pix>,1)= 1- PlX=0) = 1- (66, (0.203°(1–0.2016-03 31-(06, 060.8036) = 1-(60(1)(0.80)6) = 1 – 0.2621444 -0.737856

Answer 2

SOLUTION :

P(win on a day) = 0.20 

P(no win on a day) = 1 - 0.20 = 0.80

P( win at least on 1 prize in 6 days)

= 1 - P(no win at all in 6 days)

= 1 -  (0.80)^6

= 0.7379 (ANSWER)
