Answer:
twice
Step-by-step explanation:
to find expected value multiply probablility and number of events
0.40 times 5 = 2.0
F(x) = input the x
3x+2
multiply it by 3 and add 2
3*x+2=
3*5+2=
15+2 =
17
or if you meant 2x:
it would be the same just do:
3+2x
3+2*5
3+10
13
It would take 10 hours just like it did for Karl .
