Answer:
100
Step-by-step explanation:
9-4+3=8
5*8=40
40/2=20
20*5=100
The number of ways you can pick 3 people from 9 = 9*8*7 / 3*2*1 = 84
So chance of picking the 3 suspects = 1 / 84.
The number of ways to pick 3 from the 6 innocent people = 6*5*4 / 3*2*1 = 20
Chances of picking 3 innocent people = 20 / 84 or 5/21
Answer:

-2(x-5) < 4
-2x+10 < 4
-2x < -6
x > 3
Answer:
13
Step-by-step explanation:
The mean of a set of quantities is their sum divided by the number of them.
<h3>Mean</h3>
((p+1) +(q+2) +(r+3) +(s+4) +(t+5))/5
= (p +q +r +s +t)/5 +(1 +2 +3 +4 +5)/5
= mean(p, q, r, s, t) +15/5
= 10 +3 = 13
The mean of p+1,q+2, r+3,s+4 and t+5 is 13.
