If an experiment is consisting a fair coin twice, find: 1. The set of all possible outcomes of the experiment

2. The probability of the event of regarding at least one head

3. The probability of the event of regarding exactly one head in the two tosses

4. The probability of the event of regarding two heads

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
