Suppose that a classroom has 4 light bulbs. The probability that each individual light bulbs work is 0. 6. Suppose that each light bulb works independently of the other light bulbs. What is the probability that none of the 4 light bulbs work?.

Respuesta :

Answer:

(0.4)⁴

Step-by-step explanation:

• The probability that each individual light bulbs work is :

1 - 0. 6 = 0.4

Then

•• the probability that none of the 4 light bulbs work is :

(0.4)×(0.4)×(0.4)×(0.4)

= (0.4)⁴

= 0.0256
