Answer:
0.430
Step-by-step explanation:
Product has four parts :
For proper functioning, each part must function :
Let the 4 parts be:
A, B, C and D
Proper functioning probability :
A and B = 0.79
C and D = 0.83
For proper functioning :
P(A) * P(B) * P(C) * P(D)
0.79 * 0.79 * 0.83 * 0.83
= 0.42994249
= 0.430
