WebAnswer. 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. WebSo you see the symmetry. 1/32, 1/32. 5/32, 5/32; 10/32, 10/32. And that makes sense because the probability of getting five heads is the same as the probability of getting zero tails, and the probability of getting zero tails should be the same as the probability of getting zero heads.
