Answer: 0.0023
Step-by-step explanation:
Let X be the binomial variable that represents the number of receipts will show that the above three food items were ordered.
probability of success p = 32% = 0.32
Sample size : n= 10
Binomial probability function :
Now, the probability that eight receipts will show that the above three food items were ordered :

hence, the required probability = 0.0023
7 1\5=7x5+1=36\5
36\5 x 100=720%
