P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4
The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
Answer:
X = 45
Step-by-step explanation:
90 + X + A = 180 (angles of a triangle sum to 180)
90 + X + 45 = 180
X = 45
Step-by-step explanation:
c. ultraviolet energy
The probability = outcome/total outcomes
The total of the outcomes is the total number of the letters of the given word, then
The total outcomes = 11
The outcome is the number of letter "s" in the word
The outcome = 4, then
The probability of "s" is
To change it to percent multiply it by 100% and round it to the nearest 1 decimal place
The answer is 36.4%
Answer C
Percent of change will always be positive because the change is an absolute value. As we know, absolute value is always a positive value because you don't pay attention to the direction, only the distance is important.
