Neuroblastoma, a rare form of malignant tumor, occurs in 11 children in a million, so its probability is 0.11.
four cases of neuroblastoma occurred in cape breton, which had 13636 children. assume the number of neuroblastoma cases in a group of 13636 children follows poisson distribution.
1. assuming that neuroblastoma occurs as usual, find the mean number of cases in groups of 13636 children.

The mean number of cases in groups of 13636 children is 0.15 .

Step-by-step explanation:

Given : The probability that a child have neuroblastoma : p= 0.000011

We assume the number of neuroblastoma cases in a group of 13636 children follows Poisson distribution.

Let n= 13636

Since the  neuroblastoma occurs as usual, then the mean number of cases in groups of 13636 children would be

Hence, the mean number of cases in groups of 13636 children = 0.15
