Answer:
can you rephrase it? how many pounds are there?
Step-by-step explanation:
Answer:
455 possible ways
Step-by-step explanation:
We are told that 15 women are trying out for parts in a production of snow white.
Now, we want to find the number of ways that 3 women can be selected to play.
This is simply a combination question.
Thus;
Number of ways = C(15, 3) = 15!/((15 - 3)!(3!) = 15!/(12! × 3!) = (15 × 14 × 13 × 12!)(12! × 3 × 2 × 1)
12! will cancel out to give;
(15 × 14 × 13)/6 = 455
Answer: 0.56
Step-by-step explanation:
Given: Probability that Avacia tree grow small = 0.2
⇒Probability that Avacia tree grow large = 1-0.2=0.8 [Total probability =1]
Probability that Birch tree grow small = 0.4
⇒ Probability that Birch tree grow large= 1-0.4 = 0.6
The probability that both trees will grow to the same size = P(Both large)+P(Both small)
= 0.2 x 0.4 + 0.8 x 0.6 [Events are independent]
= 0.08+0.48
=0.56
Hence, the probability that both trees will grow to the same size = 0.56
Answer:
The probability that no boats arrive is .
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the probability of a certain is likely occur a specified period of time.
= rate.
Given that, Poisson distribution at a rate of 3 per hour.
= 3
t=2
x=0
The probability that no boats arrive is
