A decimal die is tossed three times in order to generate a sequence of three random numbers.
a. Find the probability that the sequence obtained has its numbers in increasing order from left to right; for example, 5-7-8.
b. Find the probability that the sequence obtained has its second number larger than the other two; for example, 3-6-2.
I'm not sure how to solve this.
I tried to write down the numbers that meet those requirements. I know that a die tossed three times has 216 possible outcomes.
a. I got 15 combinations, would the answer should be 15/216 ???
b. I got 55 combinations, would the answer should be 55/216 ???
Can someone explain to me how to solve it, please? Thanks
