Consider the following portion of an electric circuit with three relays. Current will flow from point a to point b if there is a
Svetradugi [14.3K]

Answer:

0.9009

Step-by-step explanation:

Let X be the event that Current will flow

Let Y be the event that the first relay which is 1 is closed

Thus, we can say that every element of Y is in X, but X possesses more elements. Thus, Y ⊂ X.

Thus, we can say that;

P(X ∩ Y) = P(Y)

Thus, given that current flowed, the probability that relay 1 functioned will be expressed as;

P(Y | X) = (P(Y ∩ X))/P(X)

From earlier, we saw that P(X ∩ Y) = P(Y). Thus;

P(Y | X) = P(Y)/P(X)

From the question, P(Y) = 0.9

Since there are 3 relays, then we have;

P(X) = 1 - 0.1³ = 0.999

Thus;

P(Y | X) = 0.9/0.999

P(Y | X) = 0.9009

Julli [10]

Answer:

50 rpm clockwise

Step-by-step explanation:

100/50 × 50/200 × 200/150 × 150/200 = 0.5

In an odd number of gears, the first and last rotate inthe same direction.

100 rpm × 0.5 = 50 rpm

Answer: 50 rpm clockwise
