a. The marginal densities
and
b. This can be obtained by integrating the joint density over [0.25, 1] x [0.5, 1]:
the probability that a subject would guess more than 20 correct in a series of 36 trials
p(X > 20.5)
= p(z > 0.83)
= 0.2033
Probability is a branch of mathematics that quantifies the likelihood of an event occurring or the likelihood of a statement being true. Probability is a number between 0 and 1, with 0 generally indicating impossibility and 1 indicating certainty. that an event will occur.
A simple example is tossing a fair (unbiased) coin. Since the coin is fair, the two outcomes (heads and tails) are equally likely. The probability of heads is the same as the probability of tails. Since no other outcome is possible, the probability of heads or tails is 1/2 (also written as 0.5 or 50%).
