2•14=28 which is the musicians
5•14=70 which would be the actors
The ratio would be 28:70
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
well, let's assume you haven't been dead for 3 years then, 30,400 a year, expressed as a unit rate per hour?
assuming a year has 365 days.
a day has 24 hours, therefore a year will have 365*24 hours.
so 30400 per year, will be 30400/(365*24) per hour, namely about 3.47031963, which we can round up to about 3 deaths per hour.
We need to correctly choose exactly 4 out of the 6 drawn numbers.
Apply hypergeometric distribution:
a=number of correctly chosen numbers = 4
A=number of correct (drawn) numbers = 6
b=number of incorrectly chosen numbers = 2
B=number of undrawn numbers = 44-6 = 38
Then by the hypergeometric distribution
P(a,b,A,B)
=C(A,a)C(B,b)/C(A+B,a+b) [C(n,r)=combination of r objects taken out of n]
=C(6,4)C(38,2)/C(44,6)
=15*703/7059052
= 10545/7059052
= 0.001494 (to the nearest millionth)
Answer: probability of winning third prize is 10545/7059052=0.001494
