Answer: The probability is 0.013
Step-by-step explanation:
Out of 80 people, 28 of them dance with the hands touching the ground.
Then, the probability of selecting at random someone that dances with the hands touching the floor is equal to the number of persons that dance in that way, divided by the total number of persons.
For the first selection, this is p1 = 28/80
now, the probability in the second selection will be 27/79, because we have selected 1 out of the 28 (and also 1 out of the 80)
for the third and the fourth we have:
p3 = 26/78
p4 = 25/77
Then the probability of the fourth events is equal to the product of the four probabilities:
P = (28/80)*(27/79)/(26/78)/(25/77) = 0.013
A. 3x-7y and -7+3x that is the correct answer
Answer:
D.) 12x + 3
Step-by-step explanation: What you have to do, is distribute the 4 inside the parentheses.
6 + 4(3x - 2) + 5
6 + 4(3x) - 4(2) + 5
6 + 12x - 8 + 5 -Now combine your like terms
6 + 12x - 3
12x + 6 - 3
12x + 3
Hope this helps you, and is the right answer.
