Answer:
Step-by-step explanation:
Starting from the top, the ant can only take four different directions, all of them going down, every direction has a probability of 1/4. For the second step, regardless of what direction the ant walked, it has 4 directions: going back (or up), to the sides (left or right) and down. If the probability of the first step is 1/4 for each direction and once the ant has moved one step, there are 4 directions with the same probability (1/4 again), the probability of taking a specific path is the multiplication of the probability of these two steps:
There are only 4 roads that can take the ant to the bottom in 2 steps, each road with a probability of 1/16, adding the probability of these 4 roads:
The probability of the ant ending up at the bottom is 
or 0.25.
Answer:
Step-by-step explanation:
We are given the following in the question:
We treat adult having blood type A as a success.
P(Blood type A) =
Then the number of Children of Juan and Maria who have blood type A follows a binomial distribution as there are
- n independent trial.
- Each trial have to outcomes(Blood type A or not)
- Probability of success is same for each success
Here,
where n is the total number of observations, x is the number of success, p is the probability of success.
Thus, for the given binomial distribution,
Hey there!
Triangle CBD is congruent to triangle ABD. This means that BD is congruent to BD by reflexive property. You have two congruent angles, and one congruent side. This would be AAS theorem. The answer is D.
I hope this helps!
Answer:
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102
Step-by-step explanation:
We can build an estimate from a sample, and this estimate will be the best estimate for the proportion of the population.
Sample:
50 subscribers
15 own fewer than 2 vehicles
Proportion:
15/50 = 0.3 = 30% own fewer than 2 vehicles.
Based on the data, what is the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles?
340 subscribers
The most reasonable estimate for this number is 0.3*340.
0.3*340 = 102
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 is 102
