Ответ:
So we look for the probability using this formula derived from the original, (total outcomes) x (percentage) = (favorable outcomes), 5x=2. That gives us the answer of 0.4 or 40%.
Ответ:
Product is multiplication.
Since the answer needs to be greater than 2 either the fraction needs to be an improper fraction ( meaning the fraction would be greater than 1) or the whole number would need to be greater than 2.
One answer would be 5 x 2/3 = 3 1/3
