The problem follows a binomial distribution with n = 6 trials and probability of success p = 0.25. We need to find the probability that fewer than 4 support increased spending, which means calculating P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3). Using the binomial probability formula, this sum equals approximately 0.9624.
