Answer:0.48

Step-by-step explanation:

Given

Machine 1 Produced 392 satisfactory pistons and 98 unsatisfactory Piston

Machine 2 Produced 360 satisfactory pistons and 240 unsatisfactory Piston

Two balls are selected from batch

Probability of getting Satisfactory Piston From machine 1 is \frac{392}{490}

Probability of getting Unsatisfactory Piston From machine 2 is \frac{360}{600}

Probability that the piston chosen from machine 1 is satisfactory and from machine 2 is unsatisfactory=\frac{392}{490}\times \frac{360}{600}

=0.8\times 0.6=0.480
