Answer:
0.1384
Step-by-step explanation:
Using binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Given n = 25, r = 4, p = 0.10, and q = 0.90:
P = ₂₅C₄ (0.10)⁴ (0.90)²⁵⁻⁴
P = 12650 (0.10)⁴ (0.90)²¹
P = 0.1384
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
Miles. You would measure it in miles because youre trying to figure out how many miles she rode for a certain amount of time.

Answer: Choice C</h3>
4/36 = 1/9
==============================================================
Explanation:
Circle the second row. This is where each of the red die results are "2"
Then look at the cases when the second die is less than "5". So we could have a 1, 2, 3, or 4 on this second die.
As you can see, there are 4 cases when the first number is a 2 (red) and the second number is less than 5 (white).
We have m = 4 cases we want out of n = 6*6 = 36 cases total.
m/n = 4/36 = 1/9 is our final answer.
