The probabilities of a machine manufacturing 0,1,2,3,4, or 5 defective parts in one day are 0.75, 0.17, 0.04, 0.025, 0.01, and 0.005, respectively. Find the mean of the probability distribution.

Answer:

0.39

Step-by-step explanation:

solution: x= number of detective parts manufactured the machine in one day

p (x=0) =0.75

p (x=1)=0.17

p(x=2)=0.04

p(x=3)=0.025

p(x=4)=0.01

p(x=5)=0.05

p(x=0)xo+p(x=1)x1+p(x=2)x2+p=(x=3)×3+p(x=4)x4+(x=5)x5

=0x0.75+1xo.17+2x0.04+3x0.025+4x0.01|+5x0.005

=0.39
