- If one ball each is drawn from 3 boxes, the first containing 3 red, 2 yellow, and 1 blue, the second box contains 2 red, 2 yellow, and 2 blue, and the third box with 1 red, 4 yellow, and 3 blue. What is the probability that all 3 balls drawn are different colors?
- In a viral pool test it is known that in a group of five (5) people, exactly one (1) will test positive. If they are tested one by one in random order for confirmation, what is the probability that only two (2) tests are needed?

- A small-time bingo card costs P100.00 for 5 games. The prize for the first three games is P5,000.00, the fourth is P10,000.00 and the last prize is P20,000.00. If 1,000 bingo cards are going to be sold and you could only win once, what is the expected value of a ticket?
- You pick a card from a deck. If it is a face card, you will win P500.00. If you get an ace, you will win P1,000. If the card you picked is red you get P100.00. For any other card, you will win nothing. Find the expected value that you can possibly win.

‘Bhartdarshan’ is an Internet-based travel agency wherein customers can see videos of the cities they plan to visit. The number of hits daily is a normally distributed random variable with a mean of 10,000 and a standard deviation of 2,400.
a. What is the probability of getting more than 12,000 hits?
b. What is the probability of getting fewer than 9,000 hits?
Ravan's dream is to win tic-tac-toe championship.to accomplish this he practices alone at home to learn the strategies of the game . your task is to identify the cell where Ravan should place his third piece so that he wins the game. Assume that each cell in the tic-tac-toe board is marked with a number as shown in the below
TIC TAC TOE
0 1 2
3 4 5
6 7 8
input:
The first line of input contain two space-seperated integers representing the cells where Ravan has placed his first two pieces
output:
output should be a single line integer representing the cell where ravan should place his final piece
explanation
sample Output 1 :
ravan's first two moves are 0 and 1 so he not 2 to win the game .because it will complete the first row so the out put is 2
sample Output 2 :
ravan's first two moves are 0 and 3 so he not 6 to win the game .because it will complete the first row so the out put is 6
Instructions:
Using the do…while() loop, continuously scan for integers, but add up only all the positive integers and store the total in one variable.
The loop shall only be terminated when the inputted integer is zero. Afterwards, print out the total of all inputted positive integers.
Input
1. A series of integers
Output
The first multiple lines will contain message prompts to input the integers.
The last line contains the total of all positive integers inputted.

Enter·n:·3
Enter·n:·4
Enter·n:·-1
Enter·n:·-5
Enter·n:·1
Enter·n:·0
Total·of·all·positives·=·10
Instructions:
Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable.
The loop shall only terminate for the following reasons:
A negative decimal number is inputted (but still included in the total sum)
The total sum reaches 100.0 or more
Input
1. A series of float numbers
Output
The first multiple lines containing message prompts for float numbers.
The last line contains the sum with 2 decimal places.
Enter·a·number:·1.1
Enter·a·number:·1.2
Enter·a·number:·1.3
Enter·a·number:·1.4
Enter·a·number:·-1.0
Sum·=·4.00
Instructions:
Using a do…while() loop, continuously scan for characters (one per line) and print it out afterwards. Remember to place a space before the character's placeholder when scanning so that the newline characters will be ignored and the correct values will be scanned.
The loop shall terminate due to either of the following reasons:
The inputted character is a vowel
The number of inputted characters has already reached 5.
For all of the test cases, it is guaranteed that if the number of inputted characters is less than 5, then there must be a vowel from among the inputted characters. Also, it is guaranteed that all the characters are in lowercase.
Input
1. A series of characters
Output
Multiple lines containing message prompts for characters.
