Vicki would like to estimate the probability of tails coming up fewer than 2 times in 3 coin flips. to do this, she has a computer randomly select 0 of 1 three times, with 0 representing heads and 1 representing tails. the results of 15 trials are shown in the table.
what is vicki's estimated probability, based on this simulation?
enter your answer as a fraction, in simplified form.

Answer with explanation:

When we toss a coin,

Probability of getting Head

Probability of getting Tail

when we flip a coin three times, we can get maximum of three heads

X=0 T, 1 T, 2 T, 3 T, that is maximum of 3 tails.

We have to estimate ,the probability of tails coming up fewer than 2 times in 3 coin flips as T is represented by 1,and Head is represented by 0.

Means, X=0,1→→Probability Distribution

Out of 15 trials, in a simulation ,there are 6 trials in which[ there is tails coming up fewer than 2 times ,=either 1 Tail or 0 tail] .

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
