The likelihood that the first question will be true in a true and false quiz where P(true) = 0.7 for each question is likely.
With a probability of 0.7 assigned to each question being true, there is a higher chance that the first question will be true compared to it being false.
However, it's important to note that this does not guarantee that the first question will be true, as probability represents the likelihood of an event occurring, not certainty.
