Acoin of questionable fairness is tossed 10 times per set of trials for two sets of trials. the outcomes are ththththht and ttthtthtth (t = tails; h = heads). which model can you most likely rule out on the basis of this simulation?
a. the probability of heads is 40%.
b. the probability of heads is 30%.
c. the probability of heads is 35%
d. the probability of heads is 70%

Therefore, The correct option is A. The probability of heads is 40%  

Step-by-step explanation:

First set of trials : THTHTHTHHT ( T = Tails ; H = Heads)

Number of heads = 5

Number of outcomes = 10

Second set of trials : TTTHTTHTTH

Number of heads = 3

Number of outcomes = 10

Now, Total number of heads in the two tosses of the coin = 5 + 3 = 8

Total number of outcomes in the two tosses of the coin = 10 + 10 = 20

Therefore, The correct option is A. The probability of heads is 40%

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
