Now applying the product rule to 1/6:-

Hence, the answer.
Answer: 0.973
Step-by-step explanation:
The probability mass function of geometric distribution is
, p= probability of success on a trial.
As per given, we have
p=0.7
The probability that we'll have at most 3 orders 

hence, the required probability = 0.973
