Answer:
2.1
Step-by-step explanation:
Given :
Radios(X):_0 ___ 1 ___2 ___ 3 ___4 ___5
P(X=x) : 0.03 0.20 0.50 0.20 0.05 0.02
The expected weekly radio sales :
Σ(X) * p(x) : (0*0.03) + (1*0.20) + (2*0.50) + (3*0.20) + (4*0.05) + (5* 0.02) = 2.1
Hence, expected weekly radio sale = 2.1

See below
Step-by-step explanation:
You order the hundreds digits, then the tens, and finally the ones.
a. 213, 290, 871, 899
b. 213, 291, 871, 899
c. 91, 312, 871, 899
d. 123, 190, 871, 899
160-4-8-12 =136
136 out of 160 participants did not win a prize, so the experimental probability is
136/160=17/20
