Cevap:
It is 0.48.
Adım adım açıklama:
1. Calculating the probability of two events happening at the same time,
light bulbs being ready for shipment and arriving on time, is the product of
probabilities of the two events calculated separately.
2. Therefor,
Probability of being ready for shipment . Probability of arriving on time =
0.80 . 0.60 = 0.48
3. 0.48 is the probability of light bulbs being ready for shipment and
arriving at the destination on time; hence the answer.
Hope this helps.
