Answer:
a) P(2)=0.270
b) P(X>3)=0.605
c) P=0.410
Step-by-step explanation:
We know that customers arrive at a grocery store at an average of 2.1 per minute. We use the Poisson distribution:
a) In this case: 
Therefore, the probability is P(2)=0.270.
b) In this case: 
Therefore, the probability is P(X>3)=0.605.
c) We know that two customers came in in the first minute. That is why we calculate the probability of at least 5 customers entering the other 2 minutes.
In this case:
Therefore, the probability is P=0.410.

Answer:
100 rupee notes= 6, 50 rupee notes=3
Step-by-step explanation:
3 x 50 = 150
6 x 100 = 600
600 + 150 = 750
and 3 x 2 = 6, so the amount of 100 rupee notes are twice the amount of 50 rupee notes.
Hope this helps :)
