Answer:
Probability = 0.275
Step-by-step explanation:
There are two possible ways for his design to be approved: Being a high-energy engine (H) and being approved or a low-energy energy (L) and being approved.
It is known that there is a 50-50 chance of the engine being high or low-energy.
The probability of approval for each type of engine (E) is given by:
Where A(E) is the approval rate for each engine.
Therefore, the probabilities of approval for each type of engine are:
The total probability of approval is the sum of both low and high-engine probabilities;
