Answer:
The probability you will get a head at least once is 50%.
Step-by-step explanation:
Since the question is asking about the probability you will get, we can assume we’re answering based on theoretical probability. This type of probability is based on logic.
A coin always has two sides, one with head and the other with tails. So we can easily represent this as half and half. 1/2 as a fraction. 0.5 as a decimal. 50% as a percent. This means that P(H) will be equal to any one of these as they are all the same. The same can be said for the probability that a head does not appear, in other words, a tail appears. The reason being that the probability is split evenly between the two. This will again mean that P(T) will equal to any one of those.
So, A = 50% and B = 50%. The probability you will get a head at least once is 50%.
Answer:
15a
Step-by-step explanation:
Because 5(a + a + a) = 5 * (3a) = 15a
Answer=0.5 hours
0.5 1
_____ =_____
0.25hr x hr
cross multiply
0.5x=0.25
divide both sides by 0.5
x=0.5 hr
It will take 0.5 hours to paint one wall
