Answer:
5/36 or approximately 13.88...%
Step-by-step explanation:
First, we need to know the probability of rolling a 2 or 3. Because there are 6 sides, the probability is 2/6
Next, we have to find the probability of rolling an even number. With the numbers:
1, 2, 3, 4, 5, 6
1, 3, 5 are odd 2, 4, 6 are even
so, the probability of rolling an even number is 3/6
Finally, multiply the probabilities:
3/6*2/6=5/36
Answer:
5/36 or about 13.88%
It form a right triangle
legnth of ladder is hypotonuse
bottom of ladder from wall distance is one leg
distance up wall is other leg
a^2+b^2=c^2
c=hypotonuse and a and b are legs
4^2+b^2=20^2
16+b^2=400
minus 16 both sides
b^2=384
sqrt both sides
b=8√6 ft
aprox
b=19.59ft from ground

Answer: 0.332 < p < 0.490
Step-by-step explanation:
We know that the confidence interval for population proportion is given by :-

, where n= sample size
= sample proportion
z* = critical z-value.
As per given , we have
n= 258
Sample proportion of college students who own a car = 
Critical z-value for 99% confidence interval is 2.576. (By z-table)
Therefore , the 99% confidence interval for the true proportion(p) of all college students who own a car will be :
Hence, a 99% confidence interval for the true proportion of all college students who own a car : 0.332 < p < 0.490
