Answer:
P(x < 3) = 0.42319
Step-by-step explanation:
From the given information:
The mean density
3
Let x be the random variable that follows a Poisson distribution.
Therefore:
for x =1, 2, 3...
However, the probability that a random quadrat contains less than 3 spatuletails can be computed as:





P(x < 3) = 0.42319
The inequality as a compound which u have to see

5m + 7/2 = -2m + 5/2
5m + 2m = 5/2 - 7/2
7m = -1
m = -1/7 <==
Answer:
