aleksklad [387]

Answer:

219.15% (2DP)

At a factory that produces pistons for cars, Machine 1 produced 174 satisfactory pistons and 116 unsatisfactory pistons today. M

m_a_m_a [10]

Answer:

$0.7$ is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory

Step-by-step explanation:

The two events are independent of each other.

Hence the probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 is equal probability of choosing satisfactory piston from Machine 1 + probability of choosing unsatisfactory piston from Machine 2

Substituting the given values we get

Probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 = $\frac{174}{174 +116} + \frac{20}{180 +20}$

= $\frac{174}{174 +116} + \frac{20}{180 +20}$

= $= \frac{174}{290} + \frac{20}{200}\\= 0.6 + 0.1\\= 0.7$
