The Poisson probability distribution function is
where
μ = mean number of successes
x = actual or expected number of successes
Given:
μ = 13
x = 5
Therefore the probability that x=5 is
P(x = 5) = (e⁻¹³*13⁵)/5!
= 0.8392/120
= 0.006994
= 0.0070 (to 4 dec. places)
Answer: 0.0070 (to 4 decimal places)
It is interesting to observe P(x) as x varies, as in the graph shown below.

Answer:
1. A 2.D
Step-by-step explanation:
G is the number of girls who attended so that will be our product.
Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so
we would multiply a decimal times the whole.
Convert 75% into a decimal
Multiply that by 12 to equal G
So the answer is A
Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.
Let set up a fraction to make the equation equivalent
1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.
so the answer is D
