John flips three pennies. (a) amy peeks and sees that the first coin lands heads. what is the probability of getting all heads

Answer- Probability of getting all heads is 0.25

Solution-

As the outcome of the first experiment is know to be Heads. So the sample space becomes

S = {(H, H, H),(H, H, T),(H, T, H),(H, T , T)}

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
