Answer:

P(x < 3) = 0.42319

Step-by-step explanation:

From the given information:

The mean density \lambda = 3

Let x be the random variable that follows a Poisson distribution.

Therefore:

\mathtt{P(x) = \dfrac{e^{-\lambda} \lambda ^x}{x!}}     for x =1, 2, 3...

However, the probability that a random quadrat contains less than 3 spatuletails can be computed as:

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

\mathtt{P(x

P(x < 3) = 0.42319

25 x (5 - 2) ➗ 5 - 12
joja [24]

Answer: 3

Step-by-step explanation:

25 x (5 - 2) ➗ 5 - 12

Applying the rule of BODMAS

- Solve task in bracket first

25 x (5 - 2) ➗ 5 - 12

= 25 x (3) ➗ 5 - 12

= 75 ➗ 5 - 12

- Solve task of division next

75 ➗ 5 - 12

= 15 - 12

= 3

Thus, the answer is 3
