Step-by-step explanation:
rest are amphibians. How many more types of reptiles are there than amphibians in the exhibits?
Answer:
There are 35 more types of reptiles than amphibians
Step-by-step explanation:
112-72=40
75-40=35
The 40 is the number of amphibians and if you do the number of reptiles minus the number of amphibians (75-40) you get how many more reptiles there are than amphibians.
The zoo has 32 more types of reptiles than amphibians. This was determined by subtracting the number of amphibians from the number of reptiles.
The subject of this question is mathematics, specifically a problem requiring the subtraction operation to determine the difference between two numbers. When you are told there are 112 types of reptiles and amphibians at the zoo and 72 of them are reptiles, you are being asked to find out how many are amphibians. To do this, you simply subtract the number of reptiles from the total number of amphibians and reptiles, which is 112 - 72 = 40. Now, the student asked how many more types of reptiles there are. Since there are 72 reptiles and 40 amphibians, you would find the difference by subtracting 40 from 72, giving the result of 32. So, there are 32 more types of reptiles than amphibians at the zoo.

Final answer:
Using the binomial probability formula, the probability that exactly 1 out of 6 seeds doesn't grow is approximately 0.119 or 11.9%.
This question revolves around the concept of binomial probability. The binomial distribution model is an appropriate statistical model here since there are a fixed number of trials (6 seed plantings), each trial (seed planting) is independent, and each trial results in one of two outcomes: success (plant grows) or failure (plant doesn’t grow).
The binomial probability formula is P(X=k) = C(n, k)*(p^k)*(q^(n-k)), where 'n' is the number of trials (6 in this case), 'k' is the number of 'successes' we're interested in (5 in this case, since we want only 1 seed - out of 6 - not to grow), 'p' is the probability of success, and 'q' is the probability of failure.
Here, to calculate the probability, p (probability of successful growth) is 0.75 and q (probability of not growing) is 0.25 (= 1 - 0.75).
So, P(5 plants grow and 1 doesn’t) = C(6, 5) * (0.75^5) * (0.25^1) = 0.119.
So, the probability that exactly 1 out of 6 seeds does not grow is approximately 0.119 or 11.9%. This scenario is also known as binomial distribution scenario.

Answer:
9.72405%
Step-by-step explanation:
Binomial Probability
(N choose k) p^k (1-p)^(n-k)
N=7 seeds planted
p= 100% - 70% = 30% = 0.3 <--- we are interested in the plant NOT growing
(1-p) = 70% = 0.7 <--- 70% chance the plant will survive and grow
k=4 <--- we want four of them to fail
The probability is:
(7 choose 4) * (0.3)^4 (0.7)^3 =
7!/(4!3!) (0.3)^4 (0.7)^3 =
(7*6*5/3*2) (0.3)^4 (0.7)^3 =
7*5 (0.3)^4 (0.7)^3 =
35 * 0.0081 * 0.343 = 0.0972405 = 9.72405%
