Answer:a) P(8 of the players numbers are drawn)=1.3×10^-8
b) P(7 of the players number are drrawn)=3.33×10^-c) P(at least 6 of the players number were drawn)=1.84×10^-4
Step-by-step explanation:
Players has 8 combinations of numbers from 1-40. The outcome S contains all the combinations of 8 out of 40
a) P(8 of the players numbers are drawn)= 1/40/8= 1.3×10^-8
There are one in hundred million chances that the draw numbers are precisely the chosen ones.
b) Number of ways of drawing 78 selected numbers from 1-40=8×(40-7)
8×32
P(7 of the players number are drawn)=8×32/40 =3.33×10^-6.
There are approximately 300,000 chances that 7 of the players numbers are chosen
c) P(at least 6 players numbers are drawn)= 32/2×(8/6) ways to draw.
P(at least 6 players numbers are drawn)=P(all 8 chosen are drawn)+P(7 players numbers drawn)+P(6 chosen are drawn) = 1+ 8 x32/40/8 +[8\6 ×32/2]
P(at least 6 players numbers are drawn) = 1.84×10^-4.
There are approximately 5400chances that at least6 of the numbers drawn are chosen by the player.

Answer: The last answer is correct
Step-by-step explanation:
BAC and BCA are the same because A=70 degrees B=70 degrees.
if the top looks exactly like the bottom or vise versa, its the same degree.
How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)
Answer:
2902
Step-by-step explanation:
Let the total number of adults within the mentioned age bracket be n=3271
The proportion of adults who used at least one prescription medication be p=88.7%=0.887
The point estimate of population is given by
where x is number of individuals in the sample with the specified characteristics and n is the sample size.
Let x be the adults who used at least one prescription medication
