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:
The time required by both persons to complete the work T = 1.458 hours
Step-by-step explanation:
Given data
Time required by Joe to clear a lot 
= 2.5 hours
Time required by his partner to clear a lot 
= 2.5 hours
Time required by both persons to complete the work by working together
T = 1.458 hours
Therefore the time required by both persons to complete the work T = 1.458 hours
