A box contains 15 resistors. Ten of them are labeled 50 Ω and the other five are labeled 100 Ω.

a. What is the probability that the first resistor is 100 Ω?

b. What is the probability that the second resistor is 100 Ω, given that the first resistor is 50 Ω?

c. What is the probability that the second resistor is 100 Ω, given that the first resistor is 100 Ω?

Answer:

Step 1 of 4:

Given a box contains 15 resistors. Here 10 of them are labeled and the other five are labeled

Step 2 of 4:

a). The aim is to find the probability that the first resistor is

Given, the total resistors are 15. Out of 15, five are labeled

Then,

=

=

Therefore, the probability that the probability that the first resistor is is
