Answer:
51 minutes.
Step-by-step explanation:
We have been given that for every 15 minutes of a show, there are two minutes to commercial. At this rate, Leila has seen 45 minutes of a show. We are asked to find the time for which Leila has been watching TV.
We will use proportions to solve our given problem.
Upon substituting our given values, we will get:
Therefore, Leila has been watching TV together for 51 minutes.

Answer:
Sample space = {(T,T), (T,H), (HT), (HH)}
Step-by-step explanation:
We are given a fair coin which when tossed one times either gives heads(H) or tails(T).
Now, the same coin is tossed two times.
1) All the possible outcomes
Tails followed by tails
Rails followed by heads
Heads followed by a tail
Heads followed by heads
2) Sample space
{(T,T), (T,H), (HT), (HH)}
3) Formula:
Using the above formula, we can compute the following probabilities.
Probability((T,T)) =
Probability((T,H)) =
Probability((H,T)) =
Probability((H, H)) =
Probability(Atleast one tails) =
Probability(Atleast one heads) =
Probability(Exactly one tails) =
Probability(Exactly one heads) =
