258 cubic inches
Since the boxes are kind of on their own—>
First box: 7*2*12 = 168
Second box: 5*2*9=90
168+90 = 258
Answer:
a) 0.0016
b) 0.0224
Step-by-step explanation:
If every question has 5 possible answers, the probability of getting the correct answer by guessing would be 0.20. The probability of getting an incorrect answer would be 0.80.
a)Find the probability she lucks out and answers all four questions correctly.
To do this, Allison would have to guess right the first, second, third AND fourth answers. Therefore, we have to multiply the probabilities:
0.20 x 0.20 x 0.20 x 0.20 = 0.0016
The probability that she answers all 4 questions correctly is 0.0016.
b) Find the probability that she passes the quiz.
To pass the quiz, she has to have three OR 4 correct answers:
- The probability that she has 3 correct answers is: 0.20 x 0.20 x 0.20 x 0.80 (since she has to have 1 correct answer and 1 incorrect one) = .0064.
- We already calculated the probability that she guesses 4 answers correctly: 0.0016.
Now, we have to sum up these two scenarios:
0.0064 + 0.016 = 0.0224.
Thus, the probability that she passes the quiz is 0.0224
Answer:
Step-by-step explanation:
Assuming a binomial distribution for the number of U.S. households that owned a computer in 2001. The formula for binomial distribution is expressed as
P(X = r) = nCr × q^(n - r) × p^r
Where
p = probability of success
q = probability of failure
n = number of sample
From the information given,
p = 56.5% = 56.5/190 = 0.565
q = 1 - p = 1 - 0.565 = 0.435
n = 3
We want to determine P(x greater than or equal to 1). This is also expressed as
1 - P(x lesser than or equal to 1)
P(x lesser than or equal to 1) = P(x = 0) + P(x =1)
P(x = 0) = 3C0 × 0.435^(3 - 0) × 0.565^0 = 0.082
P(x = 1) = 3C1 × 0.435^(3 - 1) × 0.565^1 = 0.32
P(x greater than or equal to 1) = 0.082 + 0.32 = 0.402
Quadrant one only. as altitude decreases the atmospheric pressure decreses.
