Yes, X is a binomial random variable, because: The coin is tossed in exactly the same way 100 times. Each toss results in either a head (success) or a tail (failure). One toss doesn't affect the outcome of another toss. The trials are independent. The probability of getting a head is 0.70 for each toss of the coin.

WebThis is a specific type of discrete random variable. A binomial random variable counts how often a particular event occurs in a fixed number of tries or trials. For a variable to … WebThe following is an example of applying a continuity correction. Suppose one wishes to calculate Pr(X ≤ 8) for a binomial random variable X. If Y has a distribution given by the normal approximation, then Pr(X ≤ 8) is approximated by Pr(Y ≤ 8.5). The addition of 0.5 is the continuity correction; the uncorrected normal approximation gives ...
