When a fair coin is​ flipped, the probability of its landing heads​ (H) is 0.500.50 and the probability of its landing tails​ (T

) is also 0.500.50. Make a list of all the possible arrangements for flipping a fair coin​ twice, using H for heads and T for tails. Find the probabilities of each arrangement.

Answer:

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

Step-by-step explanation:

given data

probability heads​ (H) is 0.50

probability heads​ (T) is 0.50

to find out

the probabilities of each arrangement

solution

when coin toss there are two outcome that is head or tail

and then flip 2 time

possibility are HH  HT TH  TT

so

probability (HH) = 1/4 = 0.25

probability (HT) = 1/4 = 0.25

probability (TH) = 1/4 = 0.25

probability (TT) = 1/4 = 0.25

tensa zangetsu [6.8K]

Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.  

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = \left \{ {{n \atop k} \right. p^{k}q^{n-k}

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.  

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.

k-4/3= 3

Mutiply both sides by 3 .

(3)(k-4/3)= (3)(3)

Cross out 3 and 3 , divide by 3 and then becomes k-4= 9

Move -4 to the other side

Sign changes from -4 to +4

k-4+4= 9+4

k= 13

Answer: k= 13

.....Jeremy did not make a good inference. The ratio is not in proportion to 2/15. The correct inference would be about 26 students who did not read any books in July. The sample might be biased since it was limited to those at the pool....
