Write a script to simulate the rolling of two dice. The script should use Math.random to roll the first die and again to roll the second die. The sum of the two values should then be calculated. [Note: Since each die can show an integer value from 1 to 6, the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12 the least frequent sums. Figure 10.22 shows the 36 possible combinations of the two dice. Your program should roll the dice 36,000 times. Use a one-dimensional array to tally the number of times each possible sum appears. Display the results in an HTML5 table. Also determine whether the totals are reasonable (e.g., there are six ways to roll a 7, so approximately 1/6 of all the rolls should be 7).]

this code only prints random dna letters where is the game there are the questions below Find the complement of a DNA strand: recall that a DNA strand is a combination of fouruppercase letters; A, T, C, and G. The letters A and T are complements, and the letters Cand G are complements. To find the complement of a DNA strand you must replace eachcharacter with its complement. For example, ATCGG is the complement of TAGCC andCCC is the complement of GGG. Your program must show a DNA of a predefined lengthto the player and ask for its complement.2. Find the reversed DNA strand: the order of the characters in a DNA strand should bereversed. Examples: GCTAA is the reverse of AATCG and AA is the reverse of AA. Yourprogram must show a DNA of a predefined length to the player and ask for the reversedstrand.3. Find the compressed DNA strand: all repeated characters in a DNA strand should bereplaced by the number of repeats followed by that character once. For example, 2C3ATis the compressed…
what do I add to make every letter in between 'w' and 'f' to become 'o'?.
use java programming make a program that takes in a string. This string will be altered by switching the characters by asking two indices to switch. However, there is a twist. If the index to be switched is a vowel character, find the nearest non-vowel character and switch it instead. If the distance to the left is the same as the riht one, use the right one. Furthermore, finding the nearest non-vowel character is rotational, meaning, if you are at index '0' and the non vowel character and index '1' (right direction) is a vowel character, the new index would be the last index.
I need help with this python computer science DEEP BREADTH SEARCH question. I have the layout of the code but I need help filling in the parts that say "pass" and I want you to take a picture of your output and make sure it matches the sample run below. Find a path (not the best path, but just any path) from A to Z. You see that the green path is not the shortest but it does let us navigate from start to finish. (The picture below) First, we need to know A and Z, our starting and ending points. We'll pass these into our function. I'm going to use a dictionary to represent this graph. Each node (vertex, circle) will have a name, in this case "A" and "Z" were the names of the nodes, but in the generated maps I'm going to use "Node 1", "Node 2", "Node 3", etc. Here is an example web_map web_map = { 'Node 1': ['Node 3', 'Node 2'], 'Node 2': ['Node 1', 'Node 4'], 'Node 3': ['Node 1'], 'Node 4': ['Node 2'] } Node 1 is connected to 2 and 3 for instance, and then also note that…
