You have two large bins of marbles. In bin A, 40% of the marbles are red. In bin B, 52% of the marbles are red. You select a simple random sample of 30 marbles from bin A and 40 marbles from bin B. What is the probability that the proportion of red marbles in the sample from bin A is greater than the proportion of red marbles from bin B?

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for

The right answer is option d.
