A sample of 5 light bulbs is drawn from a large collection (large enough to be considered essentially infinite), in which each bulb is good with a probability of 0.9. If you wanted to determine the probability that exactly 4 of the light bulbs in the sample are good, which of the following equations would you use?

Question

A sample of 5 light bulbs is drawn from a large collection (large enough to be considered essentially infinite), in which each bulb is good with a probability of 0.9. If you wanted to determine the probability that exactly 4 of the light bulbs in the sample are good, which of the following equations would you use?

b(1;5,0.9) = (;) 0,9ʻ0.1'
b(4; 5,0.9) = () 0.9*0.11
Option 1
Option 2
b(1;5,0.1) = (;) 0.1*0.9'
b(4; 5,0.1) = ()0.1*0.91
Transcribed Image Text:b(1;5,0.9) = (;) 0,9ʻ0.1' b(4; 5,0.9) = () 0.9*0.11 Option 1 Option 2 b(1;5,0.1) = (;) 0.1*0.9' b(4; 5,0.1) = ()0.1*0.91
