To solve, first find the total of all the sweets: 15 + 16 + 19 = 50. Then, add together the caramel chocolates and the dark chocolates: 16 + 15 = 31. To find the probability, set up a fraction with the combinatio nof caramel in dark chocolates in the numerator, and the total in the denominator: 31/50. So, Amber will have a 31 out of 50 chance to randomly pick either caramel chocolate or dark chocolate.
