if freddy tosses a coin three times, what is the probability that the coin will turn up hesds,tails,heads, tails in that order? I came up with 1/2 correct?
also the ratio length to the width of the alamo isabout 5to 3 if the width of the alamo is 63ft about how long is the alamo? would that be 37.4ft?
THANK YOU.

It would help if you proofread your questions before you posted them. You indicate three tosses with four outcomes.
The probability of any one toss = 1/2
The probability of all/both events occurring = product of the individual events.
If ratio of length to width = 5/3 and width = 63, the length will be > 63.
5/3 = x/63
Solve for x.
