This choice correctly uses the probability notation and describes the range of values for X as being between 75 and 95 inclusive, which is what the statement is saying. Choice A uses the wrong notation with the equals sign, while choice B asserts that X can only be exactly equal to both 75 and 95, which is unlikely. Choice C describes X as being exactly 75, which is not what the original statement says.
