Answer: The maximum number of refills that you can get is 7.

Solution:
3.80=1.89+0.25x
x=1.91/0.25=7.64=7(We take it as 7 because,if we need 8 cups we will jave to pay more,I think there is not such a subject of rounding decimal in sale)

Answer: the probability that the number x of correct answers is fewer than 4 is 0.61

Step-by-step explanation:

Let x be a random variable representing the answers to the SAT questions. This is a binomial distribution since the outcomes are two ways. It is either the answer is correct or incorrect. Also, the probability of success or failure is constant for each trial. The probability of success, p = 0.35

The probability of failure, q would be 1 - p = 1 - 0.35 = 0.65

We want to determine P(x < 4)

n = number of trial = 9

x = 4

From the binomial distribution calculator,

P(x < 4) = 0.61
