In a science experiment, result X is expected to occur 25% of the time and result Y is expected to occur theremaining 75% of the time. The following code segment is intended to simulate the experiment if there are100 trials.Line 1: xCount 0Line 2:yCount ← 0Line 3:REPEAT 100 TIMESLine 4:{Line 5:IF(RANDOM (1, 4) = 1)Line 6:{Line 7:xCountxCount + 1Line 8:}Line 9:IF(RANDOM (1, 4) > 1)Line 10:{Line 11:yCountyCount + 1Line 12: }Line 13: }Line 14: DISPLAY ("Result X occurred")Line 15: DISPLAY (xCount)Line 16: DISPLAY ("times and result Y occurred")Line 17: DISPLAY (yCount)Line 18: DISPLAY("times.")A programmer runs the code segment, and the following message is displayed.Result X occurred 24 times and result Y occurred 70 times.The result shows that 94 trials were counted, rather than the intended 100 trials. Which of the followingchanges to the code segment will ensure a correct simulation of the experiment?AReplacing line 9 with IF (RANDOM (1, 4) ≥ 2)BReplacing line 9 with ELSECInterchanging lines 5 and 9D Interchanging lines 7 and 11

The Issue:- The total number of trials counted (xCount + yCount) is 94, instead of 100. This…

Printing Triangles with Nested Loops Due Date: Thursday, April 13 at 11:59 PM Task Write a JAVA program that reads the height of a triangle (less than 10) from the user and then calls two void methods named plotTril and plotTri2. Each of the 2 methods should have a parameter for the height of the triangle and use printf inside of nested For loops to produce the output of the respective triangle for the user. Note that the numbers in the triangle are left-aligned. Create a project and class named HW8FirstnameLastname in NetBeans using your actual first and last names to hold your program. For height = 8, plotTril and plotTri2 will print the following triangles respectively. 12 1 1 2 1 4 2 8 4 16 8 32 16 1 2 4 1 2 4 8 1 2 4 8 4 12 2 1 844H 2 16 1 NL 1 2 48 16 32 2 1 1 724 COM 8 16 32 64 1 2 48 1 36 24 16 8 00 32 16 64 32 128 64 1 2 4 8 16 32 1 2 4 8 16 1 2 4 8 1 2 4 1 2 1
Write a program that asks a user to input the height of triangle and draw a triangle that has the following pattern. Use nested loops for this problem. If the user enter height as 4 Then the triangle output is 1 1 2 1 2 3 1 2 3 4 We make the following assumptions • There is no space between the margin and first number in each row • There could be a space after the last number on every line • There is pne space between numbers on every line • There maybe a newline at the end of last line There is one test-case to check your code, there are two hidden testcases that tests correctness of your code 376584 2469
