Fail | Low pass | Pass | High pass | Total | |
Fresno | 30 | 60 | 150 | 75 | 315 |
L.A | 70 | 150 | 400 | 80 | 700 |
Kern | 15 | 40 | 90 | 30 | 175 |
Sacromento | 50 | 80 | 250 | 50 | 430 |
Total | 165 | 330 | 890 | 235 | 1620 |
15)
P(high pass)=235/1620=0.145
16)
P(Sacromento)=50/165=0.303
17)
P(high pass/L.A)=80/700=0.114
18)
