Answer:
0.0000
Step-by-step explanation:
Given that a die is rolled 360 times. Let say that you want to use normal approximation to find the probability that the number of 4 was rolled exactly 100 times.
Here we know that getting 4 is binomial with p = 1/6 and n =360
By approximating to normal after checking conditions are satisfied we have
X = no of fours obtained is normal
with mean =
and variance =
Std dev = 7.072
X is N(60, 7.072)
For finding out prob x=100 we have to do continuity correction as
For this case we propose a rule of three:
25 ------------> 100%
2 --------------> x
Where the variable "x" represents the percentage equivalent to 2 doctors.
Thus, 2 doctors represent 8% of 25
Answer:
2 doctors represent 8% of 25
