Answer:
0.7448
Step-by-step explanation:
P(A1) =0.95
P(A2) =0.98
P(A3) =0.8
We have to find P( all three components function properly)=P(A1∩A2∩A3).
We know that the these three events are independent so,
P( all three components function properly)=P(A1∩A2∩A3)=P(A1)*P(A2)*P(A3)
P( all three components function properly)=P(A1∩A2∩A3)=0.95*0.98*0.80
P( all three components function properly)=P(A1∩A2∩A3)=0.7448
Answer:
C
Step-by-step explanation:
3.806millions is
3.804*10^7
if we the add up the two populations it equals
6.41*10^7
30 because you just have to divide it by three
