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) =
Answer:
1.2
Step-by-step explanation:
We have given the variance between - group estimate is = 30
And the variance within - group estimate is =25
Now we have to calculate the F ratio
F ratio is defined as the ratio of variance between the group and variance within the group
So F ratio
So for the given variance F ratio will be 1.2
