a. 44 x
20.000.000 = 8.800.000
100
Jadi Probabilitasnya adalah Rp. 8.800.000,-
b. 65 x
5.000.000 = 3.250.000
100
Jadi Probabilitasnya adalah
5.000.000-3.250.000 = Rp. 1.750.000,-
No.
3
Jawab
: 5000 = 1000
4000 X
X = 4000
5
=
800
4000 = 800
0,7 Y
Y = 0,14 Jadi harapan
matematikannya 0,14
No.5
Jawab
:
a. z1
= 40-50 = -10
= -1
10 10
b. z2
= 65-60 = 15 = 1,5
10 10
No.
6
Jawab
: 
= n!
= n!
1!(n-k)!
= 6!
1!(6-1)!
6 . 5! = 6
1!5!
= 4!
1!(6-1)!
=
4 . 3 ! = 4
1!3!
No.
9
Jawab:
GUNADARMA ada 9 huruf : G=1, U=1, N=1, A=3, D=1, R=1, M=1
9!
= 60480
1!1!1!3!1!1!1!
No.
10
Jawab:
x
+ 1 + 2x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 + x + 7
= 7
8
9x + 29 = 56
9x =
56 - 29
X
= 27
9
X
= 3 Jadi Umur anak A = 3 tahun
