Simply multiply the total amount of bulbs by the probability of being faulty:


2000 * 0.05 = 100


You can expect 100 bulbs to be faulty.

Hey!


The probability that a bulb is faulty is 0.05, and 2,00 bulbs are produced. You have to multiply the probability by how much was made.


[tex] Probability = 0.05 [/tex]

[tex] Amount- Made = 2,000 [/tex]


That gives you:


[tex] 0.05 \times 2000 = 100 [/tex]


[tex] \framebox{You can expect 100 bulbs to be faulty} [/tex]
